NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-doc package and not the kernel-uek-doc package as distributed by Oracle. See How to fix? for Oracle:6 relevant fixed versions and status.

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.
