DESCRIPTION:
A vulnerability has been reported in the Linux Kernel, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error when mounting CIFS shares
with certain DFS referrals, which can be exploited to trigger a
"BUG_ON()" in a client by tricking the victim into mounting from a
malicious server.
