CVE-2011-1759

Published: 02 May 2011

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.

From the Ubuntu security team

Dan Rosenberg reported an error in the old ABI compatibility layer of ARM kernels. A local attacker could exploit this flaw to cause a denial of service or gain root privileges.
