Descriptions

A flaw was found in DPDK version 19.11 and above that allows a malicious guest to cause a segmentation fault of the vhost-user backend application running on the host, which could result in a loss of connectivity for the other guests running on that host. This is caused by a missing validity check of the descriptor address in the function `virtio_dev_rx_batch_packed()`.

Se detectó un fallo en DPDK versión 19.11 y superior, que permite a un invitado malicioso causar un fallo de segmentación de la aplicación backend vhost-user que se ejecuta en el host, lo que podría resultar en una pérdida de conectividad para los otros invitados ejecutados en ese host. Esto es causado por una falta de comprobación de la validez de la dirección del descriptor en la función "virtio_dev_rx_batch_packed()".
