What it is

In 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.
