How to fix?

Upgrade Centos:7 kernel to version 0:3.10.0-123.6.3.el7 or higher.

NVD Description

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

The Netlink implementation in the Linux kernel through 3.14.1 does not provide a mechanism for authorizing socket operations based on the opener of a socket, which allows local users to bypass intended access restrictions and modify network configurations by using a Netlink socket for the (1) stdout or (2) stderr of a setuid program.
