(CVE-2021-4159)\n\n - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.\n This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object. (CVE-2021-44733)\n\n - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak because the hash table is very small. (CVE-2021-45486)\n\n - In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file. (CVE-2021-45868)\n\n - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)\n\n - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)\n\n - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.\n (CVE-2022-0492)\n\n - A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494)\n\n - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)\n\n - A flaw use after free in the Linux kernel FUSE filesystem was found in the way user triggers write(). A local user could use this flaw to get some unauthorized access to some data from the FUSE filesystem and as result potentially privilege escalation too. (CVE-2022-1011)\n\n - Due to the small table perturb size, a memory leak flaw was found in the Linux kernel's TCP source port generation algorithm in the net/ipv4/tcp.c function. This flaw allows an attacker to leak information and may cause a denial of service. (CVE-2022-1012)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain,which can cause a use- after-free.This issue needs to handle return with proper preconditions,as it can lead to a kernel information leak problem caused by a local,unprivileged attacker. (CVE-2022-1016)\n\n - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel.This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information. (CVE-2022-1353)\n\n - An issue was discovered in the Linux Kernel from 4.18 to 4.19, an improper update of sock reference in TCP pacing can lead to memory/netns leak, which can be used by remote clients. (CVE-2022-1678)\n\n - Kernel-headers includes the C header files that specify the interfacebetween the Linux kernel and userspace libraries and programs. Theheader files define structures and constants that are needed forbuilding most standard programs and are also needed for rebuilding theglibc package. (CVE-2022-1729)\n\n - In mmc_blk_read_single of block.c, there is a possible way to read kernel heap memory due to uninitialized data. This could lead to local information disclosure if reading from an SD card that triggers errors, with no additional execution privileges needed. User interaction is not needed for exploitation.\n (CVE-2022-20008)\n\n - In lg_probe and related functions of hid-lg.c and other USB HID files, there is a possible out of bounds read due to improper input validation. This could lead to local information disclosure if a malicious USB HID device were plugged in, with no additional execution privileges needed. User interaction is not needed for exploitation. (CVE-2022-20132)\n\n - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead to local escalation of privilege when opening and closing inet sockets with no additional execution privileges needed. User interaction is not needed for exploitation. (CVE-2022-20141)\n\n - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB.An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to influence mispredicted branches.Then, cache allocation can allow the attacker to obtain sensitive information. (CVE-2022-23960)\n\n - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor. (CVE-2022-24448)\n\n - A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat. (CVE-2022-27666)\n\n - usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double free. (CVE-2022-28388)\n\n - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.\n (CVE-2022-28390)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. (CVE-2022-32250)\n\n - The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are used.

{"nessus": [{"lastseen": "2023-05-18T14:45:06", "description": "According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :\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 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. (CVE-2020-26140)\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 in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets, independent of the network configuration. (CVE-2020-26142)\n\n - An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH. The WEP, WPA, WPA2, and WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. 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 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 on Samsung Galaxy S3 i9305 4.4.4 devices. The WPA, WPA2, and WPA3 implementations reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. Note that WEP is vulnerable to this attack by 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 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 was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)\n\n - In gre_handle_offloads of ip_gre.c, there is a possible page fault due to an invalid memory access. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-150694665References: Upstream kernel (CVE-2021-39633)\n\n - In fs/eventpoll.c, there is a possible use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product:\n AndroidVersions: Android kernelAndroid ID: A-204450605References: Upstream kernel (CVE-2021-39634)\n\n - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)\n\n - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.\n This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object. (CVE-2021-44733)\n\n - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak because the hash table is very small. (CVE-2021-45486)\n\n - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor.

(CVE-2020-26142)\n\n - An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH. The WEP, WPA, WPA2, and\n WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. An adversary can\n 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\n implementations accept plaintext A-MSDU frames as long as the first 8 bytes correspond to a valid RFC1042\n (i.e., LLC/SNAP) header for EAPOL. An adversary can abuse this to inject arbitrary network packets\n independent of the network configuration. (CVE-2020-26144)\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 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 Linux kernel's implementation of MIDI, where an attacker with a local account and\n the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to\n this specific memory while freed and before use causes the flow of execution to change and possibly allow\n for memory corruption or privilege escalation. The highest threat from this vulnerability is to\n confidentiality, integrity, as well as system availability. (CVE-2020-27786)\n\n - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This\n could lead to local escalation of privilege with System execution privileges needed. User interaction is\n not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:\n Upstream kernel (CVE-2021-0920)\n\n - A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users\n do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.\n (CVE-2021-20321)\n\n - An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66\n and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read\n the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process's\n memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222\n 4.19.177 5.4.99 5.10.17 5.11 (CVE-2021-21781)\n\n - An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in\n drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.\n (CVE-2021-30002)\n\n - Improper input validation in the Intel(R) Ethernet ixgbe driver for Linux before version 3.17.3 may allow\n an authenticated user to potentially enable denial of service via local access. (CVE-2021-33098)\n\n - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on\n inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)\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 - hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev\n without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.\n (CVE-2021-37159)\n\n - A use-after-free flaw was found in the Linux kernel's Bluetooth subsystem in the way user calls connect to\n the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the\n system or escalate their privileges. The highest threat from this vulnerability is to confidentiality,\n integrity, as well as system availability. (CVE-2021-3752)\n\n - A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP\n association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and\n the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)\n\n - ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss\n can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:\n the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the\n length validation was added solely for robustness in the face of anomalous host OS behavior.\n (CVE-2021-38160)\n\n - net/netfilter/nf_conntrack_standalone.c in the Linux kernel before 5.12.2 allows observation of changes in\n any net namespace because these changes are leaked into all other net namespaces. This is related to the\n NF_SYSCTL_CT_MAX, NF_SYSCTL_CT_EXPECT_MAX, and NF_SYSCTL_CT_BUCKETS sysctls. (CVE-2021-38209)\n\n - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some\n regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the\n memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)\n\n - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket\n file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race\n condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an\n improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of\n service (DOS) due to a deadlock problem. (CVE-2021-4149)\n\n - An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in\n the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could\n potentially use this flaw to crash the system or escalate privileges on the system. (CVE-2021-4157)\n\n - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces\n subsystem was found in the way users have access to some less privileged process that are controlled by\n cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of\n control groups. A local user could use this flaw to crash the system or escalate their privileges on the\n system. (CVE-2021-4197)\n\n - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows\n an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).\n (CVE-2021-43976)\n\n - In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered,\n leading to a move_data_page NULL pointer dereference. (CVE-2021-44879)\n\n - In __f2fs_setxattr in fs/f2fs/xattr.c in the Linux kernel through 5.15.11, there is an out-of-bounds\n memory access when an inode has an invalid last xattr entry. (CVE-2021-45469)\n\n - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information\n leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based\n attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)\n\n - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak\n because the hash table is very small. (CVE-2021-45486)\n\n - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the\n kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups\n v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.\n (CVE-2022-0492)\n\n - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way\n user triggers udf_file_write_iter function for the malicious UDF image.

The WEP, WPA, WPA2, and WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. 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 in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets, independent of the network configuration. (CVE-2020-26142)\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. An adversary can abuse this to exfiltrate selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. Note that WEP is vulnerable to this attack by design. (CVE-2020-26146)\n\n - In __hidinput_change_resolution_multipliers of hid-input.c, there is a possible out of bounds write due to a heap buffer overflow.

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. 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 - 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.

kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a certain comparison uses values that are not memory sizes. (CVE-2021-42252)\n\n - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)\n\n - A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption).\n This vulnerability is similar with the older CVE-2019-18808.
