Affected Products:
                    SUSE Linux Enterprise Debuginfo 11-SP4
                    SUSE Linux Enterprise Server 11-EXTRA

______________________________________________________________________________

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

Description:

   The SUSE Linux Enterprise 11 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-2020-12770: Fixed sg_remove_request call in a certain failure cases
     (bsc#1171420).
   - 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-2022-0492: Fixed a privilege escalation related to cgroups v1
     release_agent feature, which allowed bypassing namespace isolation
     unexpectedly (bsc#1195543).
   - CVE-2021-45095: Fixed refcount leak in pep_sock_accept in
     net/phonet/pep.c (bsc#1193867).
   - CVE-2021-4155: Fixed a data leak flaw that allows a local attacker to
     leak data on the XFS filesystem (bsc#1194272).
   - CVE-2020-27820: Fixed a vulnerability where a use-after-frees in
     nouveau's postclose() handler could happen if removing device
     (bsc#1179599).
   - CVE-2019-0136: Fixed an insufficient access control which allow an
     unauthenticated user to execute a denial of service (bsc#1193157).
   - CVE-2021-3753: Fixed race out-of-bounds in virtual terminal handling
     (bsc#1190025).

   The following non-security bugs were fixed:

   - kprobes: Limit max data_size of the kretprobe instances (bsc#1193669).
   - md: check the return of mddev_find() (bsc#1195109).
