An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the prl_hypervisor kext. The issue results from the lack of proper validation of user-supplied data, which can result a pointer to be leaked after the handler is done. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel.

El fallo espec\u00edfico se presenta dentro del kext prl_hypervisor. El problema resulta de una falta de comprobaci\u00f3n apropiada de los datos suministrados por el usuario, lo que puede resultar en que un puntero sea filtrado una vez finalizado el manejador.
