Summary

Security update for the Linux Kernel

Details

The SUSE Linux Enterprise 15 SP2 RT 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).

The following non-security bugs were fixed:

btrfs: check for missing device in btrfstrimfs (bsc#1195701).
lib/ioviter: initialize 'flags' in new pipebuffer (bsc#1196584).
nfsd: allow delegation state ids to be revoked and then freed (bsc#1192483).
nfsd: allow open state ids to be revoked and then freed (bsc#1192483).
nfsd: do not admin-revoke NSv4.0 state ids (bsc#1192483).
nfsd: prepare for supporting admin-revocation of state (bsc#1192483).
powerpc/pseries/ddw: Revert 'Extend upper limit for huge DMA window for persistent memory' (bsc#1195995 ltc#196394).
