CVE-2018-16871

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.
