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.
