Ubuntu Security Notice USN-110-1 – Alexander Nyberg discovered an integer overflow in the sysfs_write_file() function. A local attacker could exploit this to crash the kernel or possibly even execute arbitrary code with root privileges by writing to an user-writable file in /sys under certain low-memory conditions. However, there are very few cases where a user-writeable sysfs file actually exists. Olof Johansson discovered a Denial of Service vulnerability in the futex functions, which provide semaphores for exclusive locking of resources. A local attacker could possibly exploit this to cause a kernel deadlock.
