In the Linux kernel, the following vulnerability has been resolved: net: fix NULL pointer dereference in l3mdev_l3_rcv When delete l3s ipvlan: ip link del link eth0 ipvlan1 type ipvlan mode l3s This may cause a null pointer dereference: Call trace: ip_rcv_finish+0x48/0xd0 ip_rcv+0x5c/0x100 __netif_receive_skb_one_core+0x64/0xb0 __netif_receive_skb+0x20/0x80 process_backlog+0xb4/0x204 napi_poll+0xe8/0x294 net_rx_action+0xd8/0x22c __do_softirq+0x12c/0x354 This is because l3mdev_l3_rcv() visit dev->l3mdev_ops after ipvlan_l3s_unregister() assign the dev->l3mdev_ops to NULL. The process like this: (CPU1) | (CPU2) l3mdev_l3_rcv() | check dev->priv_flags: | master = skb->dev; | | | ipvlan_l3s_unregister() | set dev->priv_flags | dev->l3mdev_ops = NULL; | visit master->l3mdev_ops | To avoid this by do not set dev->l3mdev_ops when unregister l3s ipvlan.
