Descriptions
The hvm_set_callback_via function in arch/x86/hvm/irq.c in Xen 4.6 does not limit the number of printk console messages when logging the new callback method, which allows local HVM guest OS users to cause a denial of service via a large number of changes to the callback method (HVM_PARAM_CALLBACK_IRQ).
La función hvm_set_callback_via en arch/x86/hvm/irq.c en Xen 4.6 no limita el número de mensajes de la consola de printk cuando inicia sesión el nuevo método de llamada de retorno, lo que permite a usuarios del SO invitados de HVM locales provocar una denegación de servicio a través de un gran número de cambios en el método de llamada de retorno (HVM_PARAM_CALLBACK_IRQ).
