Se ha descubierto un problema en Xen hasta las versiones 4.10.x que permite que usuarios invitados del sistema operativo x86 HVM provoquen una denegación de servicio (número de interrupción sorprendentemente alto, sobrescritura del array y cierre inesperado del hipervisor) o ganen privilegios del hipervisor estableciendo un temporizador HPET para realizar interrupciones en el modo IO-APIC. Esto también se conoce como inyección de interrupción vHPET.
