Descriptions

The PCI backend driver in Xen, when running on an x86 system and using Linux 3.1.x through 4.3.x as the driver domain, allows local guest administrators to hit BUG conditions and cause a denial of service (NULL pointer dereference and host OS crash) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and a crafted sequence of XEN_PCI_OP_* operations, aka "Linux pciback missing sanity checks."

El controlador backend PCI en Xen, cuando se ejecuta en un sistema x86 y utiliza Linux 3.1.x hasta la versión 4.3.x como dominio de controlador, permite a administradores locales invitados alcanzar condiciones de BUG y provocar una denegación de servicio (referencia a puntero NULL y caída de SO anfitrión) aprovechando un sistema con acceso a un dispositivo físico PCI capaz de pasar a través de MSI o MSI-X y una secuencia de operaciones XEN_PCI_OP_* manipulada, también conocido como "Linux pciback missing sanity checks".
