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-2022-34918: Fixed a buffer overflow with nft_set_elem_init() that
could be used by a local attacker to escalate privileges (bnc#1201171).
CVE-2021-26341: Some AMD CPUs may transiently execute beyond
unconditional direct branches, which may potentially result in data
leakage (bsc#1201050).
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-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).
The following non-security bugs were fixed:
ALSA: hda/conexant: Fix missing beep setup (git-fixes).
ALSA: hda/realtek - Add HW8326 support (git-fixes).
ALSA: hda/realtek: Add quirk for Clevo PD70PNT (git-fixes).
ALSA: hda/realtek - ALC897 headset MIC no sound (git-fixes).
ALSA: hda/via: Fix missing beep setup (git-fixes).
arm64: ftrace: fix branch range checks (git-fixes)
ASoC: cs35l36: Update digital volume TLV (git-fixes).
ASoC: cs42l52: Correct TLV for Bypass Volume (git-fixes).
ASoC: cs42l52: Fix TLV scales for mixer controls (git-fixes).
ASoC: cs42l56: Correct typo in minimum level for SX volume controls
(git-fixes).
ASoC: cs53l30: Correct number of volume levels on SX controls
(git-fixes).
ASoC: es8328: Fix event generation for deemphasis control (git-fixes).
ASoC: nau8822: Add operation for internal PLL off and on (git-fixes).
ASoC: wm8962: Fix suspend while playing music (git-fixes).
ASoC: wm_adsp: Fix event generation for wm_adsp_fw_put() (git-fixes).
ata: libata: add qc->flags in ata_qc_complete_template tracepoint
(git-fixes).
ata: libata-core: fix NULL pointer deref in ata_host_alloc_pinfo()
(git-fixes).
bcache: avoid journal no-space deadlock by reserving 1 journal bucket
(git-fixes).
bcache: avoid unnecessary soft lockup in kworker update_writeback_rate()
(bsc#1197362).
