The vulnerability is caused due to a NULL pointer dereference error caused by a race condition within the devfs and VFS interaction. This can be exploited to e.g. execute arbitrary code with kernel privileges. NOTE: Additionally, the vendor provides an enhancement against NULL pointer exploits. SOLUTION: Update FreeBSD or apply patches.
