An update that solves 9 vulnerabilities and has 7 fixes is now available.

Description:

The SUSE Linux Enterprise 15 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:

  o CVE-2022-0001: Fixed Branch History Injection vulnerability (bsc#1191580).
  o CVE-2022-0002: Fixed Intra-Mode Branch Target Injection vulnerability (bsc#
    1191580).
  o 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)
  o 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).
  o 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).
  o CVE-2022-24959: Fixed a memory leak in yam_siocdevprivate() in drivers/net/
    hamradio/yam.c (bsc#1195897).
  o 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).
  o CVE-2022-0492: Fixed a privilege escalation related to cgroups v1
    release_agent feature, which allowed bypassing namespace isolation
    unexpectedly (bsc#1195543).
  o 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:

  o crypto: af_alg - get_page upon reassignment to TX SGL (bsc#1195840).
  o hv_netvsc: fix network namespace issues with VF support (bsc#1107207).
  o hv_netvsc: move VF to same namespace as netvsc device (bsc#1107207).
  o lib/iov_iter: initialize "flags" in new pipe_buffer (bsc#1196584).
