SUSE-SU-2020:3178-1

This update for the Linux Kernel 4.12.14-150_58 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-2020-0431: In kbd_keycode of keyboard.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (bsc#1176722)
• 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-2020-11668: Fixed an out of bounds write to the heap in drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB driver) caused by mishandling invalid descriptors (bsc#1168952).
