The following security bugs were fixed:

CVE-2020-27835: Fixed a use after free vulnerability in infiniband hfi1
 driver in the way user calls Ioctl after open dev file and fork. A local
 user could use this flaw to crash the system (bnc#1179878).

CVE-2021-0707: Fixed a use after free vulnerability in dma_buf_release
 of dma-buf.c, which may lead to local escalation of privilege with no
 additional execution privileges needed (bnc#1198437).

CVE-2021-20292: Fixed object validation prior to performing operations
 on the object in nouveau_sgdma_create_ttm in Nouveau DRM subsystem
 (bnc#1183723).

CVE-2021-20321: Fixed a race condition accessing file object in the
 OverlayFS subsystem in the way users do rename in specific way with
 OverlayFS. A local user could have used this flaw to crash the system
 (bnc#1191647).

CVE-2021-38208: Fixed a denial of service (NULL pointer dereference and
 BUG) by making a getsockname call after a certain type of failure of a
 bind call (bnc#1187055).

CVE-2021-4154: Fixed a use-after-free vulnerability in
 cgroup1_parse_param in kernel/cgroup/cgroup-v1.c, allowing a local
 privilege escalation by an attacker with user privileges by exploiting
 the fsconfig syscall parameter, leading to a container breakout and a
 denial of service on the system (bnc#1193842).

CVE-2022-0812: Fixed information leak when a file is read from RDMA
 (bsc#1196639)

CVE-2022-1158: Fixed a vulnerability in the kvm module that may lead to
 a use-after-free write or denial of service (bsc#1197660).

CVE-2022-1280: Fixed a use-after-free vulnerability in drm_lease_held in
 drivers/gpu/drm/drm_lease.c (bnc#1197914).

CVE-2022-1353: Fixed access control to kernel memory in the
 pfkey_register function in net/key/af_key.c (bnc#1198516).

CVE-2022-1419: Fixed a concurrency use-after-free in
 vgem_gem_dumb_create (bsc#1198742).

CVE-2022-1516: Fixed null-ptr-deref caused by x25_disconnect
 (bsc#1199012).

CVE-2022-28356: Fixed a refcount leak bug in net/llc/af_llc.c
 (bnc#1197391).

CVE-2022-28748: Fixed memory lead over the network by ax88179_178a
 devices (bsc#1196018).

CVE-2022-28893: Fixed a use after free vulnerability in inet_put_port
 where some sockets are not closed before xs_xprt_free() (bsc#1198330).

CVE-2022-29156: Fixed a double free vulnerability related to
 rtrs_clt_dev_release.ate (jsc#SLE-15176 bsc#1198515).

The following non-security bugs were fixed:

ACPI/APEI: Limit printable size of BERT table data (git-fixes).

ACPI: processor idle: Check for architectural support for LPI
 (git-fixes).

ACPICA: Avoid walking the ACPI Namespace if it is not there (git-fixes).

ALSA: cs4236: fix an incorrect NULL check on list iterator (git-fixes).

ALSA: hda/hdmi: fix warning about PCM count when used with SOF
 (git-fixes).

ALSA: hda/realtek: Add ... [Please see the references for more information on the vulnerabilities]");
