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)

The following non-security bugs were fixed:

exec: Force single empty string when argv is empty (bsc#1200571).");
