The root cause, as the [2] says, is because that bpf_prog_test_run_skb() run a bpf prog which redirects empty skbs. So we should determine whether the length of the packet modified by bpf prog or others like bpf_prog_test is valid before forwarding it directly.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>bpf: Don&#39;t redirect packets with invalid pkt_len</p> <p>Syzbot found an issue [1]: fq_codel_drop() try to drop a flow whitout any skbs, that is, the flow-&gt;head is null.
