CVE-2011-1759: Integer Overflow
First published: Wed Jun 13 2012(Updated: )
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.
