How to fix?

Upgrade RHEL:6 kernel-debug to version 0:2.6.32-71.14.1.el6 or higher.
This issue was patched in RHSA-2011:0007.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug package and not the kernel-debug package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The uart_get_count function in drivers/serial/serial_core.c in the Linux kernel before 2.6.37-rc1 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.
