A sufficiently large value will cause an - integer overflow in allocation size, followed by copying too much data - into the allocated buffer. + Integer overflow in the sys_oabi_semtimedop function in arch/arm/kernel + /sys_oabi-compat.c in the Linux kernel before 2.6.39 on the ARM + platform, when CONFIG_OABI_COMPAT is enabled, allows local users to gain + privileges or cause a denial of service (heap memory corruption) by + providing a crafted argument and leveraging a race condition.
