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-2021-45486: Fixed an information leak because the hash table is very
 small in net/ipv4/route.c (bnc#1194087).

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-2021-43976: Fixed a flaw that could allow an attacker (who can
 connect a crafted USB device) to cause a denial of service. (bnc#1192847)

CVE-2021-43975: Fixed a flaw in hw_atl_utils_fw_rpc_wait that could
 allow an attacker (who can introduce a crafted device) to trigger an
 out-of-bounds write via a crafted length value. (bsc#1192845)

CVE-2021-4202: Fixed NFC race condition by adding NCI_UNREG flag
 (bsc#1194529).

CVE-2021-4197: Use cgroup open-time credentials for process migraton
 perm checks (bsc#1194302).

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

CVE-2021-4149: Fixed btrfs unlock newly allocated extent buffer after
 error (bsc#1194001).

CVE-2021-4135: Fixed zero-initialize memory inside netdevsim for new
 map's value in function nsim_bpf_map_alloc (bsc#1193927).

CVE-2021-4083: Fixed a read-after-free memory flaw inside the garbage
 collection for Unix domain socket file handlers when users call close()
 and fget() simultaneouslyand can potentially trigger a race condition
 (bnc#1193727).

CVE-2021-4002: Fixed incorrect TLBs flush in hugetlbfs after
 huge_pmd_unshare (bsc#1192946).

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-2021-3564: Fixed double-free memory corruption in the Linux kernel
 HCI device initialization subsystem that could have been used by
 attaching malicious HCI TTY Bluetooth devices. A local user could use
 this flaw to crash the system (bnc#1186207).

CVE-2021-33098: Fixed a potential denial of service in Intel(R) Ethernet
 ixgbe driver due to improper input validation. (bsc#1192877)

CVE-2021-28715: Fixed issue with xen/netback to do not queue ... [Please see the references for more information on the vulnerabilities]");
