Summary
Security update for the Linux Kernel (Live Patch 13 for SLE 15 SP1)

Notes

Title of the patch
Security update for the Linux Kernel (Live Patch 13 for SLE 15 SP1)
Description of the patch
This update for the Linux Kernel 4.12.14-197_48 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). - CVE-2020-14386: Fixed a memory corruption which could have lead to an attacker gaining root privileges from unprivileged processes. The highest threat from this vulnerability is to data confidentiality and integrity (bsc#1176069). - CVE-2020-24394: The NFS server code can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support. This occurs because the current umask is not considered (bsc#1175518).
