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).");
