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

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-2022-0322: Fixed SCTP issue with account stream padding length for
 reconf chunk (bsc#1194985).

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

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

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

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

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

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


The following non-security bugs were fixed:

KVM: remember position in kvm->vcpus array (bsc#1190973).

KVM: s390: index kvm->arch.idle_mask by vcpu_idx (bsc#1190973).

SUNRPC: Add basic load balancing to the transport switch - kabi fix.
 (bnc#1192729).

SUNRPC: Add basic load balancing to the transport switch. (bnc#1192729)

SUNRPC: Fix initialisation of struct rpc_xprt_switch (bnc#1192729).

SUNRPC: Optimise transport balancing code (bnc#1192729).

SUNRPC: Replace division by multiplication in calculation of queue
 length (bnc#1192729).

SUNRPC: Skip zero-refcount transports (bnc#1192729).

USB: serial: option: add Telit FN990 compositions ... [Please see the references for more information on the vulnerabilities]");
