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-2022-1012: Fixed information leak caused by small table perturb size
 in the TCP source port generation algorithm (bsc#1199482).

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-2020-26541: Enforce the secure boot forbidden signature database
 (aka dbx) protection mechanism. (bsc#1177282)

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).

The following non-security bugs were fixed:

audit: fix a race condition with the auditd tracking code (bsc#1197170).

block: bio-integrity: Advance seed correctly for larger interval sizes
 (git-fixes).

bnxt_en: Remove the setting of dev_port (git-fixes).

bonding: fix bond_neigh_init() (git-fixes).

dm crypt: Avoid percpu_counter spinlock contention in crypt_page_alloc()
 (git-fixes).

drbd: fix duplicate array initializer (git-fixes).

drbd: remove assign_p_sizes_qlim (git-fixes).

drbd: use bdev_alignment_offset instead of queue_alignment_offset
 (git-fixes).

drbd: use bdev based limit helpers in drbd_send_sizes (git-fixes).

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

ext4: fix bug_on ext4_mb_use_inode_pa (bsc#1200810).

ext4: fix bug_on in __es_tree_search (bsc#1200809).

ext4: fix bug_on in ext4_writepages (bsc#1200872).

ext4: fix overhead calculation to account for the reserved gdt blocks
 (bsc#1200869).

ext4: fix race condition between ext4_write and ext4_convert_inline_data
 (bsc#1200807).

ext4: fix symlink file size not match to ... [Please see the references for more information on the vulnerabilities]");
