CVE-2011-4131  (opens in a new tab)
CWE-189  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 3.2.2 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). The NFSv4 implementation in the Linux kernel before 3.2.2 does not properly handle bitmap sizes in GETACL replies, which allows remote NFS servers to cause a denial of service (OOPS) by sending an excessive number of bitmap words.
