CVE-2015-8324  (opens in a new tab)
CWE-476  (opens in a new tab)

How to fix?

Upgrade Centos:6 perf to version 0:2.6.32-642.el6 or higher.

NVD Description

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

The ext4 implementation in the Linux kernel before 2.6.34 does not properly track the initialization of certain data structures, which allows physically proximate attackers to cause a denial of service (NULL pointer dereference and panic) via a crafted USB device, related to the ext4_fill_super function.
