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 xHCI component. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. 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 componente xHCI. El problema resulta de la falta de una comprobaci\u00f3n apropiada de los datos suministrados por el usuario, lo que puede resultar en un desbordamiento de enteros antes de asignar un b\u00fafer.
