Descriptions

drivers/vhost/net.c in the Linux kernel before 3.13.10, when mergeable buffers are disabled, does not properly validate packet lengths, which allows guest OS users to cause a denial of service (memory corruption and host OS crash) or possibly gain privileges on the host OS via crafted packets, related to the handle_rx and get_rx_bufs functions.

drivers/vhost/net.c en el kernel de Linux anterior a 3.13.10, cuando buffers combinables están deshabilitados, no valida debidamente los longitudes de paquetes, lo que permite a usuarios invitados del sistema operativo causar una denegación de servicio (corrupción de memoria y caída del sistema operativo anfitrión) o posiblemente ganar privilegios en el sistema operativo anfitrión a través de paquetes manipulados, relacionado con las funciones handle_rx y get_rx_bufs.
