CWE-200  (opens in a new tab)

How to fix?

Upgrade Centos:6 perf to version 0:2.6.32-71.14.1.el6 or higher.

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 ntty_ioctl_tiocgicount function in drivers/char/nozomi.c in the Linux kernel 2.6.36.1 and earlier does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call.
