SUSE: 2020:3190-1 important: the Linux Kernel (Live Patch 13 for SLE 15 SP1)
Summary
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).
