CVE-2011-1771  (opens in a new tab)
CWE-476  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 2.6.39 or higher.

Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference. The cifs_close function in fs/cifs/file.c in the Linux kernel before 2.6.39 allows local users to cause a denial of service (NULL pointer dereference and BUG) or possibly have unspecified other impact by setting the O_DIRECT flag during an attempt to open a file on a CIFS filesystem.
