Summary

Security update for the Linux Kernel

Details

The SUSE Linux Enterprise 12 SP2 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-2022-0617: Fixed a null pointer dereference in UDF file system functionality. A local user could crash the system by triggering udffilewrite_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-2022-24448: Fixed an issue in fs/nfs/dir.c. If an application sets the ODIRECTORY flag, and tries to open a regular file, nfsatomic_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).
CVE-2021-0920: Fixed a local privilege escalation due to a use-after-free bug in unix_gc (bsc#1193731).
CVE-2016-10905: Fixed a use-after-free is gfs2clearrgrpd() and readrindexentry() (bsc#1146312).

The following non-security bug was fixed:

net: sched: sch_teql: fix null-pointer dereference (bsc#1190717).
