The Linux kernel before version 4.11 is vulnerable to a NULL pointer
dereference in fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allows an
attacker controlling a CIFS server to kernel panic a client that has this
server mounted, because an empty TargetInfo field in an NTLMSSP setup
negotiation response is mishandled during session recovery.
