Affected Products:	SUSE Linux Enterprise Server 11 SP4 SUSE Linux Enterprise Server 11 SP4 LTSS 11-SP4

An update that solves 10 vulnerabilities and has three security fixes can now be installed.

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).

Special Instructions and Notes:

• Please reboot the system after installing this update.
