Ubuntu Security Notice 614-1 - It was discovered that PowerPC kernels did not correctly handle reporting certain system details. By requesting a specific set of information, a local attacker could cause a system crash resulting in a denial of service. A race condition was discovered between dnotify fcntl() and close() in the kernel. If a local attacker performed malicious dnotify requests, they could cause memory consumption leading to a denial of service, or possibly send arbitrary signals to any process. On SMP systems, a race condition existed in fcntl(). Local attackers could perform malicious locks, causing system crashes and leading to a denial of service. The tehuti network driver did not correctly handle certain IO functions. A local attacker could perform malicious requests to the driver, potentially accessing kernel memory, leading to privilege escalation or access to private system information.

Debian Security Advisory 1575-1 - A vulnerability has been discovered in the Linux kernel that may lead to a denial of service. Alexander Viro discovered a race condition in the fcntl code that may permit local users on multi-processor systems to execute parallel code paths that are otherwise prohibited and gain re-ordered access to the descriptor table.
