Announcement ID: SUSE-SU-2020:3188-1 Rating: important References: #1176012 #1176382 Cross-References: CVE-2020-14381 CVE-2020-25212 Affected Products: SUSE Linux Enterprise Module for Live Patching 15-SP1 ______________________________________________________________________________
An update that fixes two vulnerabilities is now available.
Description:
This update for the Linux Kernel 4.12.14-197_56 fixes several issues.
The following security issues were fixed:
- CVE-2020-14381: Fixed a use-after-free in the fast user mutex (futex) wait operation, which could have lead to memory corruption and possibly privilege escalation (bsc#1176011). - CVE-2020-25212: A TOCTOU mismatch in the NFS client code could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c (bsc#1176381).
