Transient execution side-channel attacks attacking the Branch History Buffer (BHB), named 'Branch Target Injection' and 'Intra-Mode Branch History Injection' are now mitigated.

The following security bugs were fixed:

CVE-2022-0001: Fixed Branch History Injection vulnerability
 (bsc#1191580).

CVE-2022-0002: Fixed Intra-Mode Branch Target Injection vulnerability
 (bsc#1191580).

CVE-2022-0617: Fixed a null pointer dereference in UDF file system
 functionality. A local user could crash the system by triggering
 udf_file_write_iter() via a malicious UDF image. (bsc#1196079)

CVE-2022-0644: Fixed a denial of service by a local user. A assertion
 failure could be triggered in kernel_read_file_from_fd() (bsc#1196155).

CVE-2021-44879: In gc_data_segment() in fs/f2fs/gc.c, special files were
 not considered, which lead to a move_data_page NULL pointer dereference
 (bsc#1195987).

CVE-2022-24959: Fixed a memory leak in yam_siocdevprivate() in
 drivers/net/hamradio/yam.c (bsc#1195897).

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

CVE-2022-0487: A use-after-free vulnerability was found in
 rtsx_usb_ms_drv_remove() in drivers/memstick/host/rtsx_usb_ms.c
 (bsc#1194516).

CVE-2022-0492: Fixed a privilege escalation related to cgroups v1
 release_agent feature, which allowed bypassing namespace isolation
 unexpectedly (bsc#1195543).

CVE-2022-24448: Fixed an issue in fs/nfs/dir.c. If an application sets
 the O_DIRECTORY flag, and tries to open a regular file,
 nfs_atomic_open() performs a regular lookup. If a regular file is found,
 ENOTDIR should have occurred, but the server instead returned
 uninitialized data in the file descriptor (bsc#1195612).

The following non-security bugs were fixed:

Bluetooth: bfusb: fix division by zero in send path (git-fixes).

Bluetooth: fix the erroneous flush_work() order (git-fixes).

EDAC/xgene: Fix deferred probing (bsc#1114648).

IB/rdmavt: Validate remote_addr during loopback atomic tests
 (bsc#1114685).

NFSv4.x: by default serialize open/close operations (bsc#1114893
 bsc#1195934). Make this work-around optional

NFSv42: Do not fail clone() unless the OP_CLONE operation failed
 (git-fixes).

NFSv42: Fix pagecache invalidation after COPY/CLONE (git-fixes).

NFSv4: Handle case where the lookup of a directory fails (git-fixes).

NFSv4: nfs_atomic_open() can race when looking up a non-regular file
 (git-fixes).

PCI: Add function 1 DMA alias quirk for Marvell 88SE9125 SATA controller
 (git-fixes).

RDMA/bnxt_re: Fix query SRQ failure (bsc#1050244).

RDMA/mlx5: Set user priority for DCT (bsc#1103991).

RDMA/netlink: Add __maybe_unused to static inline in C file
 (bsc#1046306).

Replace with an alternative fix for bsc#1185377
