CVE-2022-49066

The CVE-2022-49066 issue affects the Linux kernel’s veth path. When a decapsulated packet is fed to a veth device with act_mirred, skb_headlen() may be 0, yet veth_xmit() forwards the skb to __dev_forward_skb() which unconditionally requires ETH_HLEN bytes of linear data. The root cause is the mi...
