In the Linux kernel, the following vulnerability has been resolved:
vsock/virtio: Validate length in packet header before skb_put()
When receiving a vsock packet in the guest, only the virtqueue buffer
size is validated prior to virtio_vsock_skb_rx_put(). Unfortunately,
virtio_vsock_skb_rx_put() uses the length from the packet header as the
length argument to skb_put(), potentially resulting in SKB overflow if
the host has gone wonky.
Validate the length as advertised by the packet header before calling
virtio_vsock_skb_rx_put().
