An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the prl_naptd process. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the hypervisor.

El fallo espec\u00edfico se presenta dentro del proceso prl_naptd. El problema resulta de una falta de comprobaci\u00f3n apropiada de los datos suministrados por el usuario, lo que puede resultar un subdesbordamiento de enteros antes de escribir en la memoria.
