______________________________________________________________________________

   An update that solves 10 vulnerabilities and has 9 fixes is
   now available.

Description:

   The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various
   security and bugfixes.


   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-2022-0847: Fixed a vulnerability were a local attackers could
     overwrite data in arbitrary (read-only) files (bsc#1196584).
   - 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-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 occured, but the server instead returned
     uninitialized data in the file descriptor (bsc#1195612).

   The following non-security bugs were fixed:

   - NFSv4.x: by default serialize open/close operations (bsc#1114893
     bsc#1195934).
   - crypto: af_alg - get_page upon reassignment to TX SGL (bsc#1195840).
   - hv_netvsc: fix network namespace issues with VF support (bsc#1107207).
   - hv_netvsc: move VF to same namespace as netvsc device (bsc#1107207).
   - lib/iov_iter: initialize "flags" in new pipe_buffer (bsc#1196584).
