SUSE-SU-2022:0765-1

The SUSE Linux Enterprise 12 SP5 Azure 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 udffilewrite_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 kernelreadfilefromfd() (bsc#1196155).
• CVE-2021-44879: In gcdatasegment() in fs/f2fs/gc.c, special files were not considered, which lead to a movedatapage NULL pointer dereference (bsc#1195987).
• CVE-2022-24959: Fixed a memory leak in yam_siocdevprivate() in drivers/net/hamradio/yam.c (bsc#1195897).
• CVE-2021-45095: Fixed refcount leak in pepsockaccept in net/phonet/pep.c (bsc#1193867).
• CVE-2022-0487: A use-after-free vulnerability was found in rtsxusbmsdrvremove() in drivers/memstick/host/rtsxusbms.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 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).
