How to fix?

There is no fixed version for Centos:6 perf.

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 rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel before 4.5.5 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory by reading a Netlink message.
