A malicious guest may cause the device model to operate on uninitialized I/O vectors leading to memory corruption, crashing of the bhyve process, and possibly arbitrary code execution in the bhyve process."

Un hu\u00e9sped malicioso puede causar al modelo de dispositivo operar en vectores de E/S no inicializados, conllevando a una corrupci\u00f3n de la memoria, un bloqueo del proceso bhyve y, posiblemente, una ejecuci\u00f3n de c\u00f3digo arbitrario en el proceso bhyve."
