Description
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.
Affected configurations
• linux linux kernel (<= 4.10.15)
• debian debian linux 8.0
• debian debian linux 9.0
• canonical ubuntu linux 12.04
