CVE-2014-8559  (opens in a new tab)
CWE-400  (opens in a new tab)

How to fix?

Upgrade Centos:7 kernel-doc to version 0:3.10.0-229.20.1.el7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-doc package and not the kernel-doc package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The d_walk function in fs/dcache.c in the Linux kernel through 3.17.2 does not properly maintain the semantics of rename_lock, which allows local users to cause a denial of service (deadlock and system hang) via a crafted application.
