n the Linux kernel, the following vulnerability has been resolved: vdpa/mlx5: add validation for VIRTIO_NET_CTRL_MQ_VQ_PAIRS_SET command When control vq receives a VIRTIO_NET_CTRL_MQ_VQ_PAIRS_SET command request from the driver, presently there is no validation against the number of queue pairs to configure, or even if multiqueue had been negotiated or not is unverified. This may lead to kernel panic due to uninitialized resource for the queues were there any bogus request sent down by untrusted driver. Tie up the loose ends there.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: vdpa/mlx5: agregar validación para el comando VIRTIO_NET_CTRL_MQ_VQ_PAIRS_SET Cuando control vq recibe una solicitud de comando VIRTIO_NET_CTRL_MQ_VQ_PAIRS_SET del controlador, actualmente no hay validación contra el número de pares de colas para configurar, o incluso si La multicola se había negociado o no no está verificada. Esto puede provocar pánico en el kernel debido a recursos no inicializados para las colas si hubo alguna solicitud falsa enviada por un controlador que no es de confianza. Ata los cabos sueltos allí.
