CWE-362  (opens in a new tab)

How to fix?

Upgrade Centos:6 perf to version 0:2.6.32-220.23.1.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 Linux kernel before 3.4.5 on the x86 platform, when Physical Address Extension (PAE) is enabled, does not properly use the Page Middle Directory (PMD), which allows local users to cause a denial of service (panic) via a crafted application that triggers a race condition.
