CVE-2022-48651

CVE-2022-48651 affects the Linux kernel ipvlan path. When an AF_PACKET socket uses PACKET_QDISC_BYPASS and the default xmit path is switched, skb->mac_header may remain at 65535, yielding slab-out-of-bounds in ipvlan_xmit_mode_l2. Root causes: packet_snd() only resets skb->mac_header for SO...
