The following security bugs were fixed:
CVE-2022-29900, CVE-2022-29901: Fixed the RETBLEED attack, a new Spectre
like Branch Target Buffer attack, that can leak arbitrary kernel
information (bsc#1199657).
CVE-2022-1679: Fixed a use-after-free in the Atheros wireless driver in
the way a user forces the ath9k_htc_wait_for_target function to fail
with some input messages (bsc#1199487).
CVE-2022-20132: Fixed out of bounds read due to improper input
validation in lg_probe and related functions of hid-lg.c (bsc#1200619).
CVE-2022-33981: Fixed use-after-free in floppy driver (bsc#1200692)
CVE-2022-20141: Fixed a possible use after free due to improper locking
in ip_check_mc_rcu() (bsc#1200604).
CVE-2021-4157: Fixed an out of memory bounds write flaw in the NFS
subsystem, related to the replication of files with NFS. A user could
potentially crash the system or escalate privileges on the system
(bsc#1194013).
CVE-2022-20154: Fixed a use after free due to a race condition in
lock_sock_nested of sock.c. This could lead to local escalation of
privilege with System execution privileges needed (bsc#1200599).
CVE-2022-2318: Fixed a use-after-free vulnerability in the timer
handler in net/rose/rose_timer.c that allow attackers to crash the
system without any privileges (bsc#1201251).
CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742: Fixed
multiple potential data leaks with Block and Network devices when using
untrusted backends (bsc#1200762).
CVE-2021-26341: Some AMD CPUs may transiently execute beyond
unconditional direct branches, which may potentially result in data
leakage (bsc#1201050).
CVE-2020-26541: Enforce the secure boot forbidden signature database
(aka dbx) protection mechanism. (bsc#1177282)
CVE-2022-1974: Fixed an use-after-free that could causes kernel crash by
simulating an nfc device from user-space (bsc#1200144).
CVE-2022-1975: Fixed a bug that allows an attacker to crash the linux
kernel by simulating nfc device from user-space (bsc#1200143).
CVE-2022-1729: Fixed a sys_perf_event_open() race condition against self
(bsc#1199507).
CVE-2022-1184: Fixed a use-after-free and memory errors in ext4 when
mounting and operating on a corrupted image (bsc#1198577).
CVE-2022-21499: Lock down kgdb to prohibit secure-boot bypass
(bsc#1199426).
CVE-2019-19377: Fixed a user-after-free that could be triggered when an
attacker mounts a crafted btrfs filesystem image (bsc#1158266).
The following non-security bugs were fixed:
btrfs: tree-checker: fix incorrect printk format (bsc#1200249).
exec: Force single empty string when argv is empty (bsc#1200571).");
