CVE-2006-4342

Medium

The kernel in Red Hat Enterprise Linux 3, when running on SMP systems, allows local users to cause a denial of service (deadlock) by running the shmat function on an shm at the same time that shmctl is removing that shm (IPC_RMID), which prevents a spinlock from being unlocked.
