The following security bugs were fixed:

CVE-2022-0435: Fixed remote stack overflow in net/tipc module that
 validate domain record count on input (bsc#1195254).

CVE-2022-0330: Fixed flush TLBs before releasing backing store
 (bsc#1194880).

CVE-2022-0286: Fixed null pointer dereference in bond_ipsec_add_sa()
 that may have lead to local denial of service (bnc#1195371).

CVE-2022-22942: Fixed stale file descriptors on failed usercopy
 (bsc#1195065).

CVE-2021-45095: Fixed refcount leak in pep_sock_accept in
 net/phonet/pep.c (bnc#1193867).

CVE-2021-44733: Fixed a use-after-free exists in drivers/tee/tee_shm.c
 in the TEE subsystem, that could have occurred because of a race
 condition in tee_shm_get_from_id during an attempt to free a shared
 memory object (bnc#1193767).

CVE-2021-39657: Fixed out of bounds read due to a missing bounds check
 in ufshcd_eh_device_reset_handler of ufshcd.c. This could lead to local
 information disclosure with System execution privileges needed
 (bnc#1193864).

CVE-2021-39648: Fixed possible disclosure of kernel heap memory due to a
 race condition in gadget_dev_desc_UDC_show of configfs.c. This could
 lead to local information disclosure with System execution privileges
 needed. User interaction is not needed for exploitation (bnc#1193861).

CVE-2021-22600: Fixed double free bug in packet_set_ring() in
 net/packet/af_packet.c that could have been exploited by a local user
 through crafted syscalls to escalate privileges or deny service
 (bnc#1195184).

CVE-2020-28097: Fixed out-of-bounds read in vgacon subsystem that
 mishandled software scrollback (bnc#1187723).

CVE-2021-4159: Fixed kernel ptr leak vulnerability via BPF in
 coerce_reg_to_size (bsc#1194227).


The following security references were added to already fixed issues:

CVE-2021-39685: Fixed USB gadget buffer overflow caused by too large
 endpoint 0 requests (bsc#1193802).

ACPI: battery: Add the ThinkPad 'Not Charging' quirk (git-fixes).

ACPICA: Executer: Fix the REFCLASS_REFOF case in
 acpi_ex_opcode_1A_0T_1R() (git-fixes).

ACPICA: Fix wrong interpretation of PCC address (git-fixes).

ACPICA: Hardware: Do not flush CPU cache when entering S4 and S5
 (git-fixes).

ACPICA: Utilities: Avoid deleting the same object twice in a row
 (git-fixes).

ACPICA: actypes.h: Expand the ACPI_ACCESS_ definitions (git-fixes).

ALSA: seq: Set upper limit of processed events (git-fixes).

ASoC: mediatek: mt8173: fix device_node leak (git-fixes).

Bluetooth: Fix debugfs entry leak in hci_register_dev() (git-fixes).

Documentation: fix firewire.rst ABI file path error (git-fixes).

HID: apple: Do not reset quirks when the Fn key is not found (git-fixes).

HID: quirks: Allow inverting the absolute X/Y values (git-fixes).

HID: uhid: Fix worker ... [Please see the references for more information on the vulnerabilities]");
