Description:
A vulnerability has been reported in the Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service) and potentially gain escalated privileges.
The vulnerability is caused due to an error within the "clock_nanosleep()" function in kernel/posix-timers.c. This can be exploited to trigger a NULL-pointer dereference by calling "clock_nanosleep()" with a clock id equal to CLOCK_MONOTONIC_RAW.
The vulnerability is reported in versions 2.6.28 and later. Other versions may also be affected.
