Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 2.6.39

Description The issue is related to an integer overflow in the sys oabi semtimedop function, which can be exploited by local users to gain privileges or cause a denial of service, resulting in heap memory corruption. This can be achieved by providing a crafted argument and leveraging a race condition when CONFIG OABI COMPAT is enabled on the ARM platform.
