How to fix?

Upgrade RHEL:7 kernel-rt to version 0:3.10.0-229.20.1.rt56.141.14.el7_1 or higher.
This issue was patched in RHSA-2015:1977.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt package and not the kernel-rt package as distributed by RHEL. See How to fix? for RHEL: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.
