As vaddr and vm_pgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and potentially corrupt the kernel, resulting in a denial of service condition."

Cuando era actualizada la entrada de la tabla de p\u00e1ginas de un hu\u00e9sped, vm_pgoff era usado incorrectamente como desplazamiento para obtener el pfn de la p\u00e1gina. Como vaddr y vm_pgoff son controlables por procesos en modo usuario, este fallo permite a usuarios locales no privilegiado en el host escribir fuera de la regi\u00f3n del espacio de usuario y potencialmente corromper el kernel, resultando en una condici\u00f3n de denegaci\u00f3n de servicio"
