  - 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)

  - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged     user to gain root privileges. The bug allows to build several exploit primitives such as kernel address     information leak, arbitrary execution, etc. (CVE-2022-1729)

  - 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.Product:
    AndroidVersions: Android kernelAndroid ID: A-216481035References: Upstream kernel (CVE-2022-20008)

  - 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.Product: AndroidVersions: Android kernelAndroid ID: A-188677105References: Upstream     kernel (CVE-2022-20132)

  - 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.Product: AndroidVersions: Android     kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)

  - In lock_sock_nested of sock.c, there is a possible use after free due to a race condition. This could lead     to local escalation of privilege with System execution privileges needed. User interaction is not needed     for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-174846563References: Upstream     kernel (CVE-2022-20154)

  - In various methods of kernel base drivers, there is a possible out of bounds write due to a heap buffer     overflow.

    A-182388481References: Upstream kernel (CVE-2022-20166)

  - 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)

  - 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)

  - 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)

  - 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)

  - The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are     used. (CVE-2022-32296)

  - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init     (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different     vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an     unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data     in net/netfilter/nf_tables_api.c. (CVE-2022-34918)
