Descriptions

Use-after-free vulnerability in Hypervisor in Apple OS X before 10.11.2 allows local users to gain privileges via vectors involving VM objects.

Vulnerabilidad de uso después de liberación de memoria en Hypervisor en Apple OS X en versiones anteriores a 10.11.2 permite a usuarios locales obtener privilegios a través de vectores que involucran objetos VM.

The hv_space lock group gets an extra ref dropped when you kill a process with an AppleHV userclient; one via IOService::terminateWorker calling the AppleHVClient::free method (which calls lck_rw_free on the lock group using the pointer hanging off the global _hv variable) and secondly via the hypervisor machine_thread_destroy callback (hv_callback_thread_destroy) which also calls lck_rw_free with a lock group pointer taken from _hv.
