Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 2.6.34

Description A vulnerability exists in the Linux kernel where accessing the /sys/devices/system/clocksource/clocksource0/current clocksource endpoint on non-GENERIC TIME systems (GENERIC TIME=n) results in an OOPS.

Recommendations For Linux kernel versions prior to 2.6.34, update to version 2.6.34 or later to resolve the issue. As a temporary workaround, consider restricting access to the /sys/devices/system/clocksource/clocksource0/current clocksource endpoint to minimize the risk of exploitation.
