CVE-2011-2493  (opens in a new tab)
CWE-400  (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 Denial of Service (DoS). The ext4_fill_super function in fs/ext4/super.c in the Linux kernel before 2.6.39 does not properly initialize a certain error-report data structure, which allows local users to cause a denial of service (OOPS) by attempting to mount a crafted ext4 filesystem.
