How to fix?

Upgrade Centos:7 kernel-rt-trace-devel to version 0:3.10.0-514.rt56.420.el7 or higher.

NVD Description

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

The snd_timer_user_params function in sound/core/timer.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface.
