Against devices that support receiving non-SSP A-MSDU frames, which is mandatory as part of 802.11n, an adversary can abuse this to inject arbitrary network packets.\n\n[CVE-2020-24588](<http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-24588>) has been assigned to this vulnerability. A CVSS v3 base score of 3.5 has been assigned; the CVSS vector string is ([AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N](<https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N>)).\n\n#### 3.2.2 [IMPROPER AUTHENTICATION CWE-287](<https://cwe.mitre.org/data/definitions/287.html>)\n\nAn issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients.\n\n[CVE-2020-26139](<http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-26139>) has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been assigned; the CVSS vector string is ([AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H](<https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H>)).\n\n#### 3.2.3 [IMPROPER NEUTRALIZATION OF SPECIAL ELEMENTS IN OUTPUT CWE-74](<https://cwe.mitre.org/data/definitions/74.html>)\n\nAn issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to inject arbitrary data frames independent of the network configuration.\n\n[CVE-2020-26140](<http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-26140>) has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been assigned; the CVSS vector string is ([AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N](<https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N>)).\n\n#### 3.2.4 [IMPROPER VALIDATION OF INTEGRITY CHECK VALUE CWE-354](<https://cwe.mitre.org/data/definitions/354.html>)\n\nAn issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H.

For additional information on these vulnerabilities, including update instructions, please see the [Hitachi ABB Power Grids security advisory](<https://search.abb.com/library/Download.aspx?DocumentID=9AKK107992A4463&LanguageCode=en&DocumentPartId=&Action=Launch>).\n\nHitachi ABB Power Grids has tested and recommends the following mitigation actions, which help block known attack vectors:\n\n * Disable the Wi-Fi access on any TropOS unit where local Wi-Fi access is not required. This is achieved by NOT enabling (or disabling) the local access SSID.\n * Where Wi-Fi access is required, wherever possible ensure physical access to the local area is restricted to approved staff only.\n * Use the Wi-Fi whitelist capability to restrict Wi-Fi access to only approved personnel.\n * As the FragAttacks vulnerability is targeted at an end-user device and generally involves redirection to fraudulent websites, the installation of comprehensive firewall capabilities on company end-user devices and servers will significantly reduce the likelihood of negative outcomes.\n\nCISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities.

Also recognize VPN is only as secure as its connected devices.\n\nCISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.\n\nCISA also provides a section for [control systems security recommended practices](<https://us-cert.cisa.gov/ics/recommended-practices>) on the ICS webpage on [us-cert.cisa.gov](<https://us-cert.cisa.gov/ics>). Several recommended practices are available for reading and download, including [Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies](<https://us-cert.cisa.gov/sites/default/files/recommended_practices/NCCIC_ICS-CERT_Defense_in_Depth_2016_S508C.pdf>).\n\nAdditional mitigation guidance and recommended practices are publicly available on the [ICS webpage on us-cert.cisa.gov](<https://us-cert.cisa.gov/ics>) in the Technical Information Paper, [ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies](<https://us-cert.cisa.gov/ics/tips/ICS-TIP-12-146-01B>).\n\nOrganizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.\n\n * Do not click web links or open unsolicited attachments in email messages.\n * Refer to [Recognizing and Avoiding Email Scams](<https://us-cert.cisa.gov/sites/default/files/publications/emailscams_0905.pdf>) for more information on avoiding email scams.\n * Refer to [Avoiding Social Engineering and Phishing Attacks](<https://us-cert.cisa.gov/ncas/tips/ST04-014>) for more information on social engineering attacks.\n\nThese vulnerabilities are not exploitable remotely. No known public exploits specifically target these vulnerabilities. \n\n", "cvss3": {"exploitabilityScore": 2.8, "cvssV3": {"baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "ADJACENT_NETWORK", "availabilityImpact": "NONE", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 6.5, "vectorString": "CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 3.6}, "published": "2021-08-24T12:00:00", "type": "ics", "title": "Hitachi ABB Power Grids TropOS", "bulletinFamily": "info", "cvss2": {"severity": "LOW", "exploitabilityScore": 6.5, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "NONE", "availabilityImpact": "NONE", "integrityImpact": "PARTIAL", "baseScore": 3.3, "vectorString": "AV:A/AC:L/Au:N/C:N/I:P/A:N", "version": "2.0", "accessVector": "ADJACENT_NETWORK", "authentication": "NONE"}, "impactScore": 2.9, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2020-24586", "CVE-2020-24587", "CVE-2020-24588", "CVE-2020-26139", "CVE-2020-26140", "CVE-2020-26141", "CVE-2020-26142", "CVE-2020-26143", "CVE-2020-26144", "CVE-2020-26145", "CVE-2020-26146", "CVE-2020-26147"], "modified": "2021-08-24T12:00:00", "id": "ICSA-21-236-01", "href": "https://www.cisa.gov/news-events/ics-advisories/icsa-21-236-01", "cvss": {"score": 3.3, "vector": "AV:A/AC:L/Au:N/C:N/I:P/A:N"}}], "nessus": [{"lastseen": "2023-07-14T14:28:18", "description": "The remote SUSE Linux SLES11 / SLES_SAP11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14764-1 advisory.\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network.

An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\n - The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem.\n This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37.

An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.\n Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\n - The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem.\n This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37.

memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time. (CVE-2020-26558)\n\n - Improper access control in BlueZ may allow an authenticated user to potentially enable information disclosure via adjacent access. (CVE-2021-0129)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel. (CVE-2021-31829)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller.

(CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root.

An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.\n Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability.

(CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\n - The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem.\n This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37.

SUSE-SU-2021:1891-1 advisory.\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges.

Under the right circumstances, when another device sends fragmented frames encrypted using WEP,\n CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent\n Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary\n can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP,\n CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other\n clients even though the sender has not yet successfully authenticated to the AP. This might be abused in\n projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier\n to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation\n does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can\n abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-\n confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3\n implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process\n them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets\n independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble\n fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject\n packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP,\n CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel\n privilege escalation from the context of a network service or an unprivileged process. If\n sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the\n auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network\n service privileges to escalate to root or from the context of an unprivileged user directly if a\n BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to\n elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local\n user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI\n controller.

An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.\n Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges.

(CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\n - The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc//mem.\n This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37.

host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:1899-1 advisory.\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\n - The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem.\n This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced in ddf0322db79c (io_uring: add IORING_OP_PROVIDE_BUFFERS) (v5.7-rc1).

It was\n addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide\n buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was\n introduced in ddf0322db79c (io_uring: add IORING_OP_PROVIDE_BUFFERS) (v5.7-rc1). (CVE-2021-3491)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\",

kernel was updated to receive various security and bugfixes.\n\nThe following security bugs were fixed :\n\n - CVE-2021-33200: Enforcing incorrect limits for pointer arithmetic operations by the BPF verifier could be abused to perform out-of-bounds reads and writes in kernel memory (bsc#1186484).\n\n - CVE-2021-33034: Fixed a use-after-free when destroying an hci_chan. This could lead to writing an arbitrary values. (bsc#1186111)\n\n - CVE-2020-26139: Fixed a denial-of-service when an Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. (bnc#1186062)\n\n - CVE-2021-23134: A Use After Free vulnerability in nfc sockets allowed local attackers to elevate their privileges. (bnc#1186060)\n\n - CVE-2021-3491: Fixed a potential heap overflow in mem_rw(). This vulnerability is related to the PROVIDE_BUFFERS operation, which allowed the MAX_RW_COUNT limit to be bypassed (bsc#1185642).\n\n - CVE-2021-32399: Fixed a race condition when removing the HCI controller (bnc#1184611).\n\n - CVE-2020-24586: The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances this can be abused to inject arbitrary network packets and/or exfiltrate user data (bnc#1185859).\n\n - CVE-2020-24587: The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key.\n An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed (bnc#1185859 bnc#1185862).\n\n - CVE-2020-24588: The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.\n Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. (bnc#1185861)\n\n - CVE-2020-26147: The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments, even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used (bnc#1185859).\n\n - CVE-2020-26145: An issue was discovered with Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (bnc#1185860)\n\n - CVE-2020-26141: An issue was discovered in the ALFA driver for AWUS036H, where the Message Integrity Check (authenticity) of fragmented TKIP frames was not verified. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-confidentiality protocol.\n (bnc#1185987)\n\nThe following non-security bugs were fixed :\n\n -

CVE-2021-33200: Enforcing incorrect limits for pointer\n arithmetic operations by the BPF verifier could be\n abused to perform out-of-bounds reads and writes in\n kernel memory (bsc#1186484).\n\n - CVE-2021-33034: Fixed a use-after-free when destroying\n an hci_chan. This could lead to writing an arbitrary\n values. (bsc#1186111)\n\n - CVE-2020-26139: Fixed a denial-of-service when an Access\n Point (AP) forwards EAPOL frames to other clients even\n though the sender has not yet successfully authenticated\n to the AP. (bnc#1186062)\n\n - CVE-2021-23134: A Use After Free vulnerability in nfc\n sockets allowed local attackers to elevate their\n privileges. (bnc#1186060)\n\n - CVE-2021-3491: Fixed a potential heap overflow in\n mem_rw(). This vulnerability is related to the\n PROVIDE_BUFFERS operation, which allowed the\n MAX_RW_COUNT limit to be bypassed (bsc#1185642).\n\n - CVE-2021-32399: Fixed a race condition when removing the\n HCI controller (bnc#1184611).\n\n - CVE-2020-24586: The 802.11 standard that underpins Wi-Fi\n Protected Access (WPA, WPA2, and WPA3) and Wired\n Equivalent Privacy (WEP) doesn't require that received\n fragments be cleared from memory after (re)connecting to\n a network. Under the right circumstances this can be\n abused to inject arbitrary network packets and/or\n exfiltrate user data (bnc#1185859).\n\n - CVE-2020-24587: The 802.11 standard that underpins Wi-Fi\n Protected Access (WPA, WPA2, and WPA3) and Wired\n Equivalent Privacy (WEP) doesn't require that all\n fragments of a frame are encrypted under the same key.\n An adversary can abuse this to decrypt selected\n fragments when another device sends fragmented frames\n and the WEP, CCMP, or GCMP encryption key is\n periodically renewed (bnc#1185859 bnc#1185862).\n\n - CVE-2020-24588: The 802.11 standard that underpins Wi-Fi\n Protected Access (WPA, WPA2, and WPA3) and Wired\n Equivalent Privacy (WEP) doesn't require that the A-MSDU\n flag in the plaintext QoS header field is authenticated.\n Against devices that support receiving non-SSP A-MSDU\n frames (which is mandatory as part of 802.11n), an\n adversary can abuse this to inject arbitrary network\n packets. (bnc#1185861)\n\n - CVE-2020-26147: The WEP, WPA, WPA2, and WPA3\n implementations reassemble fragments, even though some\n of them were sent in plaintext. This vulnerability can\n be abused to inject packets and/or exfiltrate selected\n fragments when another device sends fragmented frames\n and the WEP, CCMP, or GCMP data-confidentiality protocol\n is used (bnc#1185859).\n\n - CVE-2020-26145: An issue was discovered with Samsung\n Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and\n WPA3 implementations accept second (or subsequent)\n broadcast fragments even when sent in plaintext and\n process them as full unfragmented frames. An adversary\n can abuse this to inject arbitrary network packets\n independent of the network configuration. (bnc#1185860)\n\n - CVE-2020-26141: An issue was discovered in the ALFA\n driver for AWUS036H, where the Message Integrity Check\n (authenticity) of fragmented TKIP frames was not\n verified. An adversary can abuse this to inject and\n possibly decrypt packets in WPA or WPA2 networks that\n support the TKIP data-confidentiality protocol.\n (bnc#1185987)\n\nThe following non-security bugs were fixed :\n\n -

vulnerabilities as referenced in the SUSE-SU-2021:2208-1 advisory.\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.\n Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\n - The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem.\n This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced in ddf0322db79c (io_uring: add IORING_OP_PROVIDE_BUFFERS) (v5.7-rc1).

SUSE-SU-2021:1887-1 advisory.\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\n - The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem.\n This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37.

Under the right circumstances, when another device sends fragmented frames encrypted using WEP,\n CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent\n Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary\n can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP,\n CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other\n clients even though the sender has not yet successfully authenticated to the AP. This might be abused in\n projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier\n to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation\n does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can\n abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-\n confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3\n implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process\n them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets\n independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble\n fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject\n packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP,\n CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel\n privilege escalation from the context of a network service or an unprivileged process. If\n sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the\n auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network\n service privileges to escalate to root or from the context of an unprivileged user directly if a\n BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to\n elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local\n user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI\n controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an\n hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic\n operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel\n memory, leading to local privilege escalation to root. In particular, there is a corner case where the off\n reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\n - The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the\n PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem.\n This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was\n addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide\n buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was\n introduced in ddf0322db79c (io_uring: add IORING_OP_PROVIDE_BUFFERS) (v5.7-rc1).

(CVE-2020-24587)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.\n Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\n - The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem.\n This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced in ddf0322db79c (io_uring: add IORING_OP_PROVIDE_BUFFERS) (v5.7-rc1).

SUSE-SU-2021:1913-1 advisory.\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\n - The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem.\n This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced in ddf0322db79c (io_uring: add IORING_OP_PROVIDE_BUFFERS) (v5.7-rc1).

affected by multiple vulnerabilities as referenced in the USN-5000-2 advisory.\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.\n Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux kernel in versions before 5.12.0-rc4. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. (CVE-2021-3506)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel. (CVE-2021-31829)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.", "cvss3": {}, "published": "2021-09-08T00:00:00", "type": "nessus", "title": "Ubuntu 20.04 LTS : Linux kernel (KVM) vulnerabilities (USN-5000-2)", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2020-24586", "CVE-2020-24587", "CVE-2020-24588", "CVE-2020-26139", "CVE-2020-26141", "CVE-2020-26145", "CVE-2020-26147", "CVE-2021-23133", "CVE-2021-23134", "CVE-2021-31829", "CVE-2021-32399", "CVE-2021-33034", "CVE-2021-33200", "CVE-2021-3506", "CVE-2021-3609"], "modified": "2023-10-20T00:00:00", "cpe": ["cpe:/o:canonical:ubuntu_linux:20.04:-:lts", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1041-kvm"], "id": "UBUNTU_USN-5000-2.NASL", "href": "https://www.tenable.com/plugins/nessus/153131", "sourceData": "#%NASL_MIN_LEVEL 70300\n##\n# (C) Tenable Network Security, Inc.\n#\n# The descriptive text and package checks in this plugin were\n# extracted from Ubuntu Security Notice USN-5000-2.

A bounds check failure allows a local attacker to gain access to\n out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest\n threat from this vulnerability is to system availability. (CVE-2021-3506)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel\n privilege escalation from the context of a network service or an unprivileged process. If\n sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the\n auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network\n service privileges to escalate to root or from the context of an unprivileged user directly if a\n BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to\n elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local\n user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading\n to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not\n protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized\n data that might represent sensitive information previously operated on by the kernel. (CVE-2021-31829)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI\n controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an\n hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic\n operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel\n memory, leading to local privilege escalation to root. In particular, there is a corner case where the off\n reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\", value:\"https://ubuntu.com/security/notices/USN-5000-2\");\n script_set_attribute(attribute:\"solution\", value:\n\"Update the affected kernel package.\");\n script_set_cvss_base_vector(\"CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C\");\n script_set_cvss_temporal_vector(\"CVSS2#E:F/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:F/RL:O/RC:C\");\n script_set_attribute(attribute:\"cvss_score_source\", value:\"CVE-2021-33200\");\n\n script_set_attribute(attribute:\"exploitability_ease\", value:\"Exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"true\");\n\n script_set_attribute(attribute:\"vuln_publication_date\", value:\"2021/04/19\");\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2021/06/25\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2021/09/08\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:canonical:ubuntu_linux:20.04:-:lts\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1041-kvm\");\n script_set_attribute(attribute:\"stig_severity\", value:\"I\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_family(english:\"Ubuntu Local Security Checks\");\n\n script_copyright(english:\"Ubuntu Security Notice (C) 2021-2023 Canonical, Inc. / NASL script (C) 2021-2023 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n\n script_dependencies(\"ssh_get_info.nasl\", \"linux_alt_patch_detect.nasl\");\n script_require_keys(\"Host/cpu\", \"Host/Ubuntu\", \"Host/Ubuntu/release\", \"Host/Debian/dpkg-l\");\n\n exit(0);\n}\n\ninclude('debian_package.inc');\ninclude('ksplice.inc');\n\nif ( ! get_kb_item('Host/local_checks_enabled') ) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED);\nvar os_release = get_kb_item('Host/Ubuntu/release');\nif ( isnull(os_release) ) audit(AUDIT_OS_NOT, 'Ubuntu');\nos_release = chomp(os_release);\nif (!

Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.\n Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux kernel in versions before 5.12.0-rc4. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. (CVE-2021-3506)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel. (CVE-2021-31829)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.", "cvss3": {}, "published": "2021-06-23T00:00:00", "type": "nessus", "title": "Ubuntu 18.04 LTS / 20.04 LTS : Linux kernel vulnerabilities (USN-5000-1)", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2020-24586", "CVE-2020-24587", "CVE-2020-24588", "CVE-2020-26139", "CVE-2020-26141", "CVE-2020-26145", "CVE-2020-26147", "CVE-2021-23133", "CVE-2021-23134", "CVE-2021-31829", "CVE-2021-32399", "CVE-2021-33034", "CVE-2021-33200", "CVE-2021-3506", "CVE-2021-3609"], "modified": "2023-10-20T00:00:00", "cpe": ["cpe:/o:canonical:ubuntu_linux:18.04:-:lts", "cpe:/o:canonical:ubuntu_linux:20.04:-:lts", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1018-gkeop", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1038-raspi", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1046-gcp", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1048-oracle", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1051-aws", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1051-azure", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-77-generic", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-77-generic-lpae", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-77-lowlatency"], "id": "UBUNTU_USN-5000-1.NASL", "href": "https://www.tenable.com/plugins/nessus/150957", "sourceData": "#%NASL_MIN_LEVEL 70300\n##\n# (C) Tenable Network Security, Inc.\n#\n# The descriptive text and package checks in this plugin were\n# extracted from Ubuntu Security Notice USN-5000-1.

USN-4997-1 advisory.\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.\n Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux kernel in versions before 5.12.0-rc4. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. (CVE-2021-3506)\n\n - A flaw null pointer dereference in the Nitro Enclaves kernel driver was found in the way that Enclaves VMs forces closures on the enclave file descriptor. A local user of a host machine could use this flaw to crash the system or escalate their privileges on the system. (CVE-2021-3543)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.11.15. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper validation of user-supplied eBPF programs prior to executing them.\n An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-13661. (CVE-2021-31440)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel. (CVE-2021-31829)\n\n - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. (CVE-2021-32399)\n\n - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.", "cvss3": {}, "published": "2021-06-23T00:00:00", "type": "nessus", "title": "Ubuntu 21.04 : Linux kernel vulnerabilities (USN-4997-1)", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2020-24586", "CVE-2020-24587", "CVE-2020-24588", "CVE-2020-26139", "CVE-2020-26141", "CVE-2020-26145", "CVE-2020-26147", "CVE-2021-23133", "CVE-2021-23134", "CVE-2021-31440", "CVE-2021-31829", "CVE-2021-32399", "CVE-2021-33034", "CVE-2021-33200", "CVE-2021-3506", "CVE-2021-3543", "CVE-2021-3609"], "modified": "2023-01-17T00:00:00", "cpe": ["cpe:/o:canonical:ubuntu_linux:21.04", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.11.0-1009-azure", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.11.0-1010-oracle", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.11.0-1011-aws", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.11.0-1011-gcp", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.11.0-1012-raspi", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.11.0-1012-raspi-nolpae", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.11.0-22-generic", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.11.0-22-generic-64k", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.11.0-22-generic-lpae", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.11.0-22-lowlatency", "p-cpe:/a:canonical:ubuntu_linux:linux-image-aws", "p-cpe:/a:canonical:ubuntu_linux:linux-image-azure", "p-cpe:/a:canonical:ubuntu_linux:linux-image-gcp", "p-cpe:/a:canonical:ubuntu_linux:linux-image-generic", "p-cpe:/a:canonical:ubuntu_linux:linux-image-generic-64k", "p-cpe:/a:canonical:ubuntu_linux:linux-image-generic-64k-hwe-20.04", "p-cpe:/a:canonical:ubuntu_linux:linux-image-generic-64k-hwe-20.04-edge", "p-cpe:/a:canonical:ubuntu_linux:linux-image-generic-hwe-20.04", "p-cpe:/a:canonical:ubuntu_linux:linux-image-generic-hwe-20.04-edge", "p-cpe:/a:canonical:ubuntu_linux:linux-image-generic-lpae", "p-cpe:/a:canonical:ubuntu_linux:linux-image-generic-lpae-hwe-20.04", "p-cpe:/a:canonical:ubuntu_linux:linux-image-generic-lpae-hwe-20.04-edge", "p-cpe:/a:canonical:ubuntu_linux:linux-image-gke", "p-cpe:/a:canonical:ubuntu_linux:linux-image-lowlatency", "p-cpe:/a:canonical:ubuntu_linux:linux-image-lowlatency-hwe-20.04", "p-cpe:/a:canonical:ubuntu_linux:linux-image-lowlatency-hwe-20.04-edge", "p-cpe:/a:canonical:ubuntu_linux:linux-image-oem-20.04", "p-cpe:/a:canonical:ubuntu_linux:linux-image-oracle", "p-cpe:/a:canonical:ubuntu_linux:linux-image-raspi", "p-cpe:/a:canonical:ubuntu_linux:linux-image-raspi-nolpae", "p-cpe:/a:canonical:ubuntu_linux:linux-image-virtual", "p-cpe:/a:canonical:ubuntu_linux:linux-image-virtual-hwe-20.04", "p-cpe:/a:canonical:ubuntu_linux:linux-image-virtual-hwe-20.04-edge"], "id": "UBUNTU_USN-4997-1.NASL", "href": "https://www.tenable.com/plugins/nessus/150953", "sourceData": "#%NASL_MIN_LEVEL 70300\n##\n# (C) Tenable Network Security, Inc.\n#\n# The descriptive text and package checks in this plugin were\n# extracted from Ubuntu Security Notice USN-4997-1.

require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.\n (CVE-2020-24586)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)\n\n - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.\n Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)\n\n - A vulnerability was found in Linux Kernel where refcount leak in llcp_sock_bind() causing use-after-free which might lead to privilege escalations. (CVE-2020-25670)\n\n - A vulnerability was found in Linux Kernel, where a refcount leak in llcp_sock_connect() causing use-after- free which might lead to privilege escalations. (CVE-2020-25671)\n\n - A memory leak vulnerability was found in Linux kernel in llcp_sock_connect (CVE-2020-25672)\n\n - A vulnerability was found in Linux kernel where non-blocking socket in llcp_sock_connect() leads to leak and eventually hanging-up the system. (CVE-2020-25673)\n\n - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. (CVE-2020-26139)\n\n - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data- confidentiality protocol. (CVE-2020-26141)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26145)\n\n - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory. Specifically, for sequences of pointer arithmetic operations, the pointer modification performed by the first operation is not correctly accounted for when restricting subsequent operations. (CVE-2021-29155)\n\n - This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.11.15. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper validation of user-supplied eBPF programs prior to executing them.\n An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-13661. (CVE-2021-31440)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel. (CVE-2021-31829)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.", "cvss3": {}, "published": "2021-06-23T00:00:00", "type": "nessus", "title": "Ubuntu 20.04 LTS : Linux kernel vulnerabilities (USN-4999-1)", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2020-24586", "CVE-2020-24587", "CVE-2020-24588", "CVE-2020-25670", "CVE-2020-25671", "CVE-2020-25672", "CVE-2020-25673", "CVE-2020-26139", "CVE-2020-26141", "CVE-2020-26145", "CVE-2020-26147", "CVE-2021-23133", "CVE-2021-29155", "CVE-2021-31440", "CVE-2021-31829", "CVE-2021-33200", "CVE-2021-3609"], "modified": "2023-10-20T00:00:00", "cpe": ["cpe:/o:canonical:ubuntu_linux:20.04:-:lts", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.8.0-1033-oracle", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.8.0-1035-gcp", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.8.0-1036-azure", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.8.0-1038-aws", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.8.0-59-generic", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.8.0-59-generic-64k", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.8.0-59-generic-lpae", "p-cpe:/a:canonical:ubuntu_linux:linux-image-5.8.0-59-lowlatency"], "id": "UBUNTU_USN-4999-1.NASL", "href": "https://www.tenable.com/plugins/nessus/150954", "sourceData": "#%NASL_MIN_LEVEL 70300\n##\n# (C) Tenable Network Security, Inc.\n#\n# The descriptive text and package checks in this plugin were\n# extracted from Ubuntu Security Notice USN-4999-1.

(CVE-2021-3543)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)\n\n - This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.11.15. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper validation of user-supplied eBPF programs prior to executing them.\n An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-13661. (CVE-2021-31440)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel.

In particular, there is a corner case where the off\n reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.\n (CVE-2021-33200)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\", value:\"https://ubuntu.com/security/notices/USN-4997-2\");\n script_set_attribute(attribute:\"solution\", value:\n\"Update the affected packages.\");\n script_set_cvss_base_vector(\"CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C\");\n script_set_cvss_temporal_vector(\"CVSS2#E:F/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:F/RL:O/RC:C\");\n script_set_attribute(attribute:\"cvss_score_source\", value:\"CVE-2021-3543\");\n script_set_attribute(attribute:\"cvss3_score_source\", value:\"CVE-2021-33200\");\n\n script_set_attribute(attribute:\"exploitability_ease\", value:\"Exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"true\");\n\n script_set_attribute(attribute:\"vuln_publication_date\", value:\"2021/04/19\");\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2021/06/25\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2021/09/08\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:canonical:ubuntu_linux:21.04\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-buildinfo-5.11.0-1009-kvm\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-headers-5.11.0-1009-kvm\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-headers-kvm\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.11.0-1009-kvm\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-kvm\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-unsigned-5.11.0-1009-kvm\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-kvm\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-kvm-headers-5.11.0-1009\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-kvm-tools-5.11.0-1009\");\n script_set_attrib
