The following security bugs were fixed:

CVE-2022-0185: Incorrect param length parsing in legacy_parse_param
 which could have led to a local privilege escalation (bsc#1194517).

CVE-2022-0322: Fixed a denial of service in SCTP sctp_addto_chunk
 (bsc#1194985).

CVE-2021-4197: Fixed a cgroup issue where lower privileged processes
 could write to fds of lower privileged ones that could lead to privilege
 escalation (bsc#1194302).

CVE-2021-46283: nf_tables_newset in net/netfilter/nf_tables_api.c in the
 Linux kernel allowed local users to cause a denial of service (NULL
 pointer dereference and general protection fault) because of the missing
 initialization for nft_set_elem_expr_alloc. A local user can set a
 netfilter table expression in their own namespace (bnc#1194518).

CVE-2021-4135: Fixed an information leak in the nsim_bpf_map_alloc
 function (bsc#1193927).

CVE-2021-4202: Fixed a race condition during NFC device remove which
 could lead to a use-after-free memory corruption (bsc#1194529)

CVE-2021-4083: A read-after-free memory flaw was found in the Linux
 kernel's garbage collection for Unix domain socket file handlers in the
 way users call close() and fget() simultaneously and can potentially
 trigger a race condition. This flaw allowed a local user to crash the
 system or escalate their privileges on the system. (bnc#1193727).

CVE-2021-4149: Fixed a locking condition in btrfs which could lead to
 system deadlocks (bsc#1194001).

CVE-2021-45485: In the IPv6 implementation net/ipv6/output_core.c has an
 information leak because of certain use of a hash table which, although
 big, doesn't properly consider that IPv6-based attackers can typically
 choose among many IPv6 source addresses (bnc#1194094).

CVE-2021-45486: In the IPv4 implementation net/ipv4/route.c has an
 information leak because the hash table is very small (bnc#1194087).

The following non-security bugs were fixed:

ACPI: APD: Check for NULL pointer after calling devm_ioremap()
 (git-fixes).

ACPI: Add stubs for wakeup handler functions (git-fixes).

ACPI: scan: Create platform device for BCM4752 and LNV4752 ACPI nodes
 (git-fixes).

ALSA: PCM: Add missing rwsem around snd_ctl_remove() calls (git-fixes).

ALSA: ctl: Fix copy of updated id with element read/write (git-fixes).

ALSA: drivers: opl3: Fix incorrect use of vp->state (git-fixes).

ALSA: hda/hdmi: Disable silent stream on GLK (git-fixes).

ALSA: hda/realtek - Add headset Mic support for Lenovo ALC897 platform
 (git-fixes).

ALSA: hda/realtek - Fix silent output on Gigabyte X570 Aorus Master
 after reboot from Windows (git-fixes).

ALSA: hda/realtek: Add a quirk for HP OMEN 15 mute LED (git-fixes).

ALSA: hda/realtek: Add quirk for ASRock NUC Box 1100 (git-fixes).

ALSA: hda/realtek: Amp init fixup for HP ZBook 15 G6 (git-fixes).
