Description Prasad Pandit 2014-09-29 13:07:03 UTC
Linux kernel built with the Network Filesystem CIFS support(CONFIG_CIFS) along
with the support for SMB2 and SMB3 network file systems(CONFIG_CIFS_SMB2) is
vulnerable to a NULL pointer dereference flaw. It could occur while mounting
the remote file system share.

A remote attacker could use this flaw to crash the client systems resulting in DoS.
