**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 2.6.34 **Description** The issue allows local users to cause a denial of service, resulting in a system hang, by performing a read or write operation on the video output control state. This is due to the lack of proper access restriction to the video output control state in the thinkpad acpi.c driver when the X.Org X server is used on ThinkPad devices. **Recommendations** For Linux kernel versions prior to 2.6.34, update to version 2.6.34 or later to resolve the issue.
