In the Linux kernel, the following vulnerability has been resolved: bonding: provide a net pointer to __skb_flow_dissect() After 3cbf4ffba5ee ("net: plumb network namespace into __skb_flow_dissect") we have to provide a net pointer to __skb_flow_dissect(), either via skb->dev, skb->sk, or a user provided pointer. In the following case, syzbot was able to cook a bare skb.
