In the Linux kernel, the following vulnerability has been resolved:

vsock/virtio: fix potential unbounded skb queue

virtio_transport_inc_rx_pkt() checks vvs->rx_bytes + len > vvs->buf_alloc.

virtio_transport_recv_enqueue() skips coalescing for packets with VIRTIO_VSOCK_SEQ_EOM.

If fed with packets with len == 0 and VIRTIO_VSOCK_SEQ_EOM, a very large number of packets can be queued because vvs->rx_bytes stays at 0.

Fix this by estimating the skb metadata size:

(Number of skbs in the queue) * SKB_TRUESIZE(0)
