Security update for the Linux Kernel (Live Patch 15 for SLE 15 SP1)

Notes

Title of the patch
Security update for the Linux Kernel (Live Patch 15 for SLE 15 SP1)
Description of the patch
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).
