CWE-200  (opens in a new tab)

How to fix?

Upgrade Oracle:7 perf to version 0:3.10.0-514.el7 or higher.
This issue was patched in ELSA-2016-2574.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Oracle. See How to fix? for Oracle: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.
