 https://git.kernel.org/linus/01310bb7c9c98752cc763b36532fab028e0f8f81
Description:
 A flaw was found in the Linux kernel's NFS implementation, all versions 3.x
 and all versions 4.x up to 4.20. An attacker, who is able to mount an
 exported NFS filesystem, is able to trigger a null pointer dereference by
 using an invalid NFS sequence. This can panic the machine and deny access
 to the NFS server. Any outstanding disk writes to the NFS server will be
 lost.
