An update that solves three vulnerabilities and has two security fixes can now be installed.
Description:
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 btrfs_trim_fs (bsc#1195701).
- lib/iov_iter: initialize "flags" in new pipe_buffer (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).
