The highest threat from this vulnerability is to system availability. (CVE-2021-31916)\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-2020-26140)\n\n - A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was found in the way user uses trace ring buffer in a specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.\n (CVE-2021-3679)\n\n - The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee (bpf, ringbuf: Deny reserve of buffers larger than ringbuf) (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37.

An adversary can abuse this to inject arbitrary data frames independent of the network configuration. (CVE-2020-26143)\n\n - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext A-MSDU frames as long as the first 8 bytes correspond to a valid RFC1042 (i.e., LLC/SNAP) header for EAPOL. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. (CVE-2020-26144)\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 on Samsung Galaxy S3 i9305 4.4.4 devices. The WPA, WPA2, and WPA3 implementations reassemble fragments with non-consecutive packet numbers.

(CVE-2020-36386)\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 - 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 - 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 - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H.

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 - 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 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 flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in the way user attach malicious HCI TTY Bluetooth device.

(CVE-2020-24502)\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 - Insufficient access control in some Intel(R) Ethernet E810 Adapter drivers for Linux before version 1.0.4 may allow an authenticated user to potentially enable information disclosure via local access.\n (CVE-2020-24503)\n\n - Uncontrolled resource consumption in some Intel(R) Ethernet E810 Adapter drivers for Linux before version 1.0.4 may allow an authenticated user to potentially enable denial of service via local access.\n (CVE-2020-24504)\n\n - An issue was discovered in __split_huge_pmd in mm/huge_memory.c in the Linux kernel before 5.7.5.

(CVE-2020-26146)\n\n - An issue was discovered in the Linux kernel before 5.8.1. net/bluetooth/hci_event.c has a slab out-of-\n bounds read in hci_extended_inquiry_result_evt, aka CID-51c19bf3d5cf. (CVE-2020-36386)\n\n - An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable\n out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre\n mitigations and obtain sensitive information from kernel memory. Specifically, for sequences of pointer\n arithmetic operations, the pointer modification performed by the first operation is not correctly\n accounted for when restricting subsequent operations. (CVE-2021-29155)\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 - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent\n Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a\n network. 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 - 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 - 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 - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent\n 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\n adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)\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 flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in\n the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the\n system. This flaw affects all the Linux kernel versions starting from 3.13. (CVE-2021-3564)\n\n - Improper access control in BlueZ may allow an authenticated user to potentially enable information\n disclosure via adjacent access. (CVE-2021-0129)\n\n - kernel: overlayfs: Mounting overlayfs inside an unprivileged user namespace can reveal files\n (CVE-2021-3732)\n\n - Improper input validation in some Intel(R) Ethernet E810 Adapter drivers for Linux before version 1.0.4\n and before version 1.4.29.0 for Windows*, may allow an authenticated user to potentially enable a denial\n of service via local access. (CVE-2020-24502)\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 - Insufficient access control in some Intel(R) Ethernet E810 Adapter drivers for Linux before version 1.0.4\n may allow an authenticated user to potentially enable information disclosure via local access.\n (CVE-2020-24503)\n\n - Uncontrolled resource consumption in some Intel(R) Ethernet E810 Adapter drivers for Linux before version\n 1.0.4 may allow an authenticated user to potentially enable denial of service via local access.\n (CVE-2020-24504)\n\n - An issue was discovered in __split_huge_pmd in mm/huge_memory.c in the Linux kernel before 5.7.5. The\n copy-on-write implementation can grant unintended write access because of a race condition in a THP\n mapcount check, aka CID-c444eb564fb1. (CVE-2020-29368)\n\n - There is a vulnerability in the linux kernel versions higher than 5.2 (if kernel compiled with config\n params CONFIG_BPF_SYSCALL=y , CONFIG_BPF=y , CONFIG_CGROUPS=y , CONFIG_CGROUP_BPF=y ,\n CONFIG_HARDENED_USERCOPY not set, and BPF hook to getsockopt is registered). As result of BPF execution,\n the local user can trigger bug in __cgroup_bpf_run_filter_getsockopt() function that can lead to heap\n overflow (because of non-hardened usercopy). The impact of attack could be deny of service or possibly\n privileges escalation. (CVE-2021-20194)\n\n - kernel: eBPF 32-bit source register truncation on div/mod (CVE-2021-3600)\n\n - A flaw was found in the Linux kernel netfilter implementation in versions prior to 5.5-rc7. A user with\n root (CAP_SYS_ADMIN) access is able to panic the system when issuing netfilter netflow commands.\n (CVE-2021-3635)\n\n - kernel: NULL pointer dereference in llsec_key_alloc() in net/mac802154/llsec.c (CVE-2021-3659)\n\n - An issue was discovered in the Linux kernel before 5.11.11. tipc_nl_retrieve_key in net/tipc/node.c does\n not properly validate certain data sizes, aka CID-0217ed2848e8.

(CVE-2020-27777)\n\n - An issue was discovered in __split_huge_pmd in mm/huge_memory.c in the Linux kernel before 5.7.5. The copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check, aka CID-c444eb564fb1. (CVE-2020-29368)\n\n - A locking inconsistency issue was discovered in the tty subsystem of the Linux kernel through 5.9.13.\n drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c may allow a read-after-free attack against TIOCGSID, aka CID-c8bcd9c5be24. (CVE-2020-29660)\n\n - mwifiex_cmd_802_11_ad_hoc_start in drivers/net/wireless/marvell/mwifiex/join.c in the Linux kernel through 5.10.4 might allow remote attackers to execute arbitrary code via a long SSID value, aka CID-5c455c5ab332.\n (CVE-2020-36158)\n\n - An issue was discovered in the Linux kernel before 5.8.10. virt/kvm/kvm_main.c has a kvm_io_bus_unregister_dev memory leak upon a kmalloc failure, aka CID-f65886606c2d.

(CVE-2020-36386)\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 - nbd_add_socket in drivers/block/nbd.c in the Linux kernel through 5.10.12 has an ndb_queue_rq use-after- free that could be triggered by local attackers (with access to the nbd device) via an I/O request at a certain point during device setup, aka CID-b98e762e3d71. (CVE-2021-3348)\n\n - The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee (bpf, ringbuf: Deny reserve of buffers larger than ringbuf) (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced via 457f44363a88 (bpf: Implement BPF ring buffer and verifier support for it) (v5.8-rc1). (CVE-2021-3489)\n\n - A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the system. This flaw affects all the Linux kernel versions starting from 3.13. (CVE-2021-3564)\n\n - A use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev() together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(), hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their privileges on the system. This flaw affects the Linux kernel versions prior to 5.13-rc5. (CVE-2021-3573)\n\n - A flaw was found in the Linux kernel netfilter implementation in versions prior to 5.5-rc7. A user with root (CAP_SYS_ADMIN) access is able to panic the system when issuing netfilter netflow commands.\n (CVE-2021-3635)\n\n - A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was found in the way user uses trace ring buffer in a specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.\n (CVE-2021-3679)\n\n - There is a vulnerability in the linux kernel versions higher than 5.2 (if kernel compiled with config params CONFIG_BPF_SYSCALL=y , CONFIG_BPF=y , CONFIG_CGROUPS=y , CONFIG_CGROUP_BPF=y , CONFIG_HARDENED_USERCOPY not set, and BPF hook to getsockopt is registered). As result of BPF execution, the local user can trigger bug in __cgroup_bpf_run_filter_getsockopt() function that can lead to heap overflow (because of non-hardened usercopy). The impact of attack could be deny of service or possibly privileges escalation. (CVE-2021-20194)\n\n - A flaw was found in the Linux kernel in versions before 5.4.92 in the BPF protocol. This flaw allows an attacker with a local account to leak information about kernel internal addresses. The highest threat from this vulnerability is to confidentiality. (CVE-2021-20239)\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 fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A stall on CPU can occur because a retry loop continually finds the same bad inode, aka CID-775c5033a0d1. (CVE-2021-28950)\n\n - In intel_pmu_drain_pebs_nhm in arch/x86/events/intel/ds.c in the Linux kernel through 5.11.8 on some Haswell CPUs, userspace applications (such as perf-fuzzer) can cause a system crash because the PEBS status in a PEBS record is mishandled, aka CID-d88d05a9e0b6. (CVE-2021-28971)\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 - An issue was discovered in the Linux kernel before 5.11.11. tipc_nl_retrieve_key in net/tipc/node.c does not properly validate certain data sizes, aka CID-0217ed2848e8. (CVE-2021-29646)\n\n - An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows attackers to cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf.\n (CVE-2021-29650)\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 - An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi- device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with special user (CAP_SYS_ADMIN) privilege 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-2021-31916)\n\n - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads to writing an arbitrary value. (CVE-2021-33033)\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": "2022-02-09T00:00:00", "type": "nessus", "title": "AlmaLinux 8 : kernel (ALSA-2021:4356)", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2019-14615", "CVE-2020-0427", "CVE-2020-24502", "CVE-2020-24503", "CVE-2020-24504", "CVE-2020-24586", "CVE-2020-24587", "CVE-2020-24588", "CVE-2020-26139", "CVE-2020-26140", "CVE-2020-26141", "CVE-2020-26143", "CVE-2020-26144", "CVE-2020-26145", "CVE-2020-26146", "CVE-2020-26147", "CVE-2020-27777", "CVE-2020-29368", "CVE-2020-29660", "CVE-2020-36158", "CVE-2020-36312", "CVE-2020-36386", "CVE-2021-0129", "CVE-2021-20194", "CVE-2021-20239", "CVE-2021-23133", "CVE-2021-28950", "CVE-2021-28971", "CVE-2021-29155", "CVE-2021-29646", "CVE-2021-29650", "CVE-2021-31440", "CVE-2021-31829", "CVE-2021-31916", "CVE-2021-33033", "CVE-2021-33200", "CVE-2021-3348", "CVE-2021-3489", "CVE-2021-3564", "CVE-2021-3573", "CVE-2021-3600", "CVE-2021-3635", "CVE-2021-3659", "CVE-2021-3679", "CVE-2021-3732"], "modified": "2023-11-13T00:00:00", "cpe": ["p-cpe:/a:alma:linux:bpftool", "p-cpe:/a:alma:linux:kernel", "p-cpe:/a:alma:linux:kernel-abi-stablelists", "p-cpe:/a:alma:linux:kernel-core", "p-cpe:/a:alma:linux:kernel-cross-headers", "p-cpe:/a:alma:linux:kernel-debug", "p-cpe:/a:alma:linux:kernel-debug-core", "p-cpe:/a:alma:linux:kernel-debug-devel", "p-cpe:/a:alma:linux:kernel-debug-modules", "p-cpe:/a:alma:linux:kernel-debug-modules-extra", "p-cpe:/a:alma:linux:kernel-devel", "p-cpe:/a:alma:linux:kernel-headers", "p-cpe:/a:alma:linux:kernel-modules", "p-cpe:/a:alma:linux:kernel-modules-extra", "p-cpe:/a:alma:linux:kernel-tools", "p-cpe:/a:alma:linux:kernel-tools-libs", "p-cpe:/a:alma:linux:kernel-tools-libs-devel", "p-cpe:/a:alma:linux:perf", "p-cpe:/a:alma:linux:python3-perf", "cpe:/o:alma:linux:8"], "id": "ALMA_LINUX_ALSA-2021-4356.NASL", "href": "https://www.tenable.com/plugins/nessus/157497", "sourceData": "#%NASL_MIN_LEVEL 70300\n##\n# (C) Tenable Network Security, Inc.\n#\n# The package checks in this plugin were extracted from\n# AlmaLinux Security Advisory ALSA-2021:4356.\n##\n\ninclude('deprecated_nasl_level.inc');\ninclude('compat.inc');\n\nif (description)\n{\n script_id(157497);\n script_version(\"1.4\");\n script_set_attribute(attribute:\"plugin_modification_date\", value:\"2023/11/13\");\n\n script_cve_id(\n \"CVE-2019-14615\",\n \"CVE-2020-0427\",\n \"CVE-2020-24502\",\n \"CVE-2020-24503\",\n \"CVE-2020-24504\",\n \"CVE-2020-24586\",\n \"CVE-2020-24587\",\n \"CVE-2020-24588\",\n \"CVE-2020-26139\",\n \"CVE-2020-26140\",\n \"CVE-2020-26141\",\n \"CVE-2020-26143\",\n \"CVE-2020-26144\",\n \"CVE-2020-26145\",\n \"CVE-2020-26146\",\n \"CVE-2020-26147\",\n \"CVE-2020-27777\",\n \"CVE-2020-29368\",\n \"CVE-2020-29660\",\n \"CVE-2020-36158\",\n \"CVE-2020-36312\",\n \"CVE-2020-36386\",\n \"CVE-2021-0129\",\n \"CVE-2021-3348\",\n \"CVE-2021-3489\",\n \"CVE-2021-3564\",\n \"CVE-2021-3573\",\n \"CVE-2021-3600\",\n \"CVE-2021-3635\",\n \"CVE-2021-3659\",\n \"CVE-2021-3679\",\n \"CVE-2021-3732\",\n \"CVE-2021-20194\",\n \"CVE-2021-20239\",\n \"CVE-2021-23133\",\n \"CVE-2021-28950\",\n \"CVE-2021-28971\",\n \"CVE-2021-29155\",\n \"CVE-2021-29646\",\n \"CVE-2021-29650\",\n \"CVE-2021-31440\",\n \"CVE-2021-31829\",\n \"CVE-2021-31916\",\n \"CVE-2021-33033\",\n \"CVE-2021-33200\"\n );\n script_xref(name:\"ALSA\", value:\"2021:4356\");\n script_xref(name:\"IAVA\", value:\"2021-A-0223-S\");\n script_xref(name:\"IAVA\", value:\"2021-A-0222-S\");\n\n script_name(english:\"AlmaLinux 8 : kernel (ALSA-2021:4356)\");\n\n script_set_attribute(attribute:\"synopsis\", value:\n\"The remote AlmaLinux host is missing one or more security updates.\");\n script_set_attribute(attribute:\"description\", value:\n\"The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the\nALSA-2021:4356 advisory.\n\n - Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor\n Graphics may allow an unauthenticated user to potentially enable information disclosure via local access.\n (CVE-2019-14615)\n\n - In create_pinctrl of core.c, there is a possible out of bounds read due to a use after free.

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 on Samsung Galaxy S3 i9305 4.4.4 devices. The WPA, WPA2, and WPA3 implementations\n reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate\n selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the\n WEP, CCMP, or GCMP data-confidentiality protocol is used. Note that WEP is vulnerable to this attack by\n design. (CVE-2020-26146)\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 flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked\n down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries\n platform) a root like local user could use this flaw to further increase their privileges to that of a\n running kernel. (CVE-2020-27777)\n\n - An issue was discovered in __split_huge_pmd in mm/huge_memory.c in the Linux kernel before 5.7.5. The\n copy-on-write implementation can grant unintended write access because of a race condition in a THP\n mapcount check, aka CID-c444eb564fb1. (CVE-2020-29368)\n\n - A locking inconsistency issue was discovered in the tty subsystem of the Linux kernel through 5.9.13.\n drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c may allow a read-after-free attack against TIOCGSID,\n aka CID-c8bcd9c5be24. (CVE-2020-29660)\n\n - mwifiex_cmd_802_11_ad_hoc_start in drivers/net/wireless/marvell/mwifiex/join.c in the Linux kernel through\n 5.10.4 might allow remote attackers to execute arbitrary code via a long SSID value, aka CID-5c455c5ab332.\n (CVE-2020-36158)\n\n - An issue was discovered in the Linux kernel before 5.8.10. virt/kvm/kvm_main.c has a\n kvm_io_bus_unregister_dev memory leak upon a kmalloc failure, aka CID-f65886606c2d. (CVE-2020-36312)\n\n - An issue was discovered in the Linux kernel before 5.8.1. net/bluetooth/hci_event.c has a slab out-of-\n bounds read in hci_extended_inquiry_result_evt, aka CID-51c19bf3d5cf. (CVE-2020-36386)\n\n - Improper access control in BlueZ may allow an authenticated user to potentially enable information\n disclosure via adjacent access. (CVE-2021-0129)\n\n - nbd_add_socket in drivers/block/nbd.c in the Linux kernel through 5.10.12 has an ndb_queue_rq use-after-\n free that could be triggered by local attackers (with access to the nbd device) via an I/O request at a\n certain point during device setup, aka CID-b98e762e3d71. (CVE-2021-3348)\n\n - The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size\n was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel\n and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee (bpf, ringbuf: Deny\n reserve of buffers larger than ringbuf) (v5.13-rc4) and backported to the stable kernels in v5.12.4,\n v5.11.21, and v5.10.37. It was introduced via 457f44363a88 (bpf: Implement BPF ring buffer and verifier\n support for it) (v5.8-rc1). (CVE-2021-3489)\n\n - A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in\n the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the\n system. This flaw affects all the Linux kernel versions starting from 3.13. (CVE-2021-3564)\n\n - A use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way\n user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev()\n together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(),\n hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their\n privileges on the system. This flaw affects the Linux kernel versions prior to 5.13-rc5. (CVE-2021-3573)\n\n - A flaw was found in the Linux kernel netfilter implementation in versions prior to 5.5-rc7. A user with\n root (CAP_SYS_ADMIN) access is able to panic the system when issuing netfilter netflow commands.\n (CVE-2021-3635)\n\n - A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was\n found in the way user uses trace ring buffer in a specific way. Only privileged local users (with\n CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.\n (CVE-2021-3679)\n\n - There is a vulnerability in the linux kernel versions higher than 5.2 (if kernel compiled with config\n params CONFIG_BPF_SYSCALL=y , CONFIG_BPF=y , CONFIG_CGROUPS=y , CONFIG_CGROUP_BPF=y ,\n CONFIG_HARDENED_USERCOPY not set, and BPF hook to getsockopt is registered). As result of BPF execution,\n the local user can trigger bug in __cgroup_bpf_run_filter_getsockopt() function that can lead to heap\n overflow (because of non-hardened usercopy). The impact of attack could be deny of service or possibly\n privileges escalation. (CVE-2021-20194)\n\n - A flaw was found in the Linux kernel in versions before 5.4.92 in the BPF protocol. This flaw allows an\n attacker with a local account to leak information about kernel internal addresses. The highest threat from\n this vulnerability is to confidentiality. (CVE-2021-20239)\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 - An issue was discovered in fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A stall on CPU can occur\n because a retry loop continually finds the same bad inode, aka CID-775c5033a0d1. (CVE-2021-28950)\n\n - In intel_pmu_drain_pebs_nhm in arch/x86/events/intel/ds.c in the Linux kernel through 5.11.8 on some\n Haswell CPUs, userspace applications (such as perf-fuzzer) can cause a system crash because the PEBS\n status in a PEBS record is mishandled, aka CID-d88d05a9e0b6. (CVE-2021-28971)\n\n - An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable\n out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre\n mitigations and obtain sensitive information from kernel memory. Specifically, for sequences of pointer\n arithmetic operations, the pointer modification performed by the first operation is not correctly\n accounted for when restricting subsequent operations. (CVE-2021-29155)\n\n - An issue was discovered in the Linux kernel before 5.11.11. tipc_nl_retrieve_key in net/tipc/node.c does\n not properly validate certain data sizes, aka CID-0217ed2848e8. (CVE-2021-29646)\n\n - An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows attackers to\n cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h\n lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf.\n (CVE-2021-29650)\n\n - This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel\n 5.11.15. An attacker must first obtain the ability to execute low-privileged code on the target system in\n order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The\n 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\n 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\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 - An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-\n device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with\n special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory leading to a system crash or\n a leak of internal kernel information. The highest threat from this vulnerability is to system\n availability. (CVE-2021-31916)\n\n - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because\n the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads\n to writing an arbitrary value. (CVE-2021-33033)\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\",

As result of BPF execution, the local user can trigger bug in __cgroup_bpf_run_filter_getsockopt() function that can lead to heap overflow (because of non-hardened usercopy). The impact of attack could be deny of service or possibly privileges escalation. NOTE! Mageia kernel configs have HARDENED_USERCOPY enabled by default, making this an non-issue when using prebuilt kernels (CVE-2021-20194). An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel. A userland application can read the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process\u2019s memory at a specific offset to trigger this vulnerability (CVE-2021-21781). An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service requests to the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be encountered. In one case, an error encountered earlier might be discarded by later processing, resulting in the caller assuming successful mapping, and hence subsequent operations trying to access space that wasn't mapped. In another case, internal state would be insufficiently updated, preventing safe recovery from the error (CVE-2021-26930). An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests (such as out of memory conditions), it isn't correct to assume a plain bug. Memory allocations potentially causing such crashes occur only when Linux is running in PV mode, though (CVE-2021-26931). An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one is reported to the backend driver, and the backend driver then loops over the results, performing follow-up actions based on the success or failure of each operation. Unfortunately, when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively implying their success from the success of related batch elements. In other cases, errors resulting from one batch element lead to further batch elements not being inspected, and hence successful ones to not be possible to properly unmap upon error recovery. Only systems with Linux backends running in PV mode are vulnerable. Linux backends run in HVM / PVH modes are not vulnerable (CVE-2021-26932).
