CVE-2007-0006

Current Description

The key serial number collision avoidance code in the key_alloc_serial function in Linux kernel 2.6.9 up to 2.6.20 allows local users to cause a denial of service (crash) via vectors that trigger a null dereference, as originally reported as "spinlock CPU recursion."

Evaluator Description

The scheme for selecting serial numbers was changed from incrementing a counter to random number selection, increasing the likelihood of a serial number collision.
