   An update that fixes four vulnerabilities is now available.


   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).
