The next iteration calls hlist_del() on it\nagain, writing LIST_POISON1 to LIST_POISON2 [1].\n\nBesides device deletion, the flush is also reachable from RTM_DELMDB\nwith NLM_F_BULK.\n\nFix by re-reading the next entry after the remotes were flushed. The\ncurrent entry cannot be removed by this flush, as source lists can only\nbe configured on (*, G) entries and the removed entries are (S, G)\nentries. It is therefore still linked and its next pointer reflects the\nremovals.\n\n[1]\nBUG: KASAN: wild-memory-access in vxlan_mdb_entry_put.part.0+0x328/0x588\nWrite of size 8 at addr dead000000000122 by task ip/327\n\nCPU: 3 UID: 1000 PID: 327 Comm: ip Not tainted 7.2.0-rc7 #2 PREEMPT\nCall trace:\n vxlan_mdb_entry_put.part.0+0x328/0x588\n vxlan_mdb_flush+0x1d8/0x25c\n vxlan_mdb_fini+0x8c/0x100\n vxlan_uninit+0x1c/0x7c\n unregister_netdevice_many_notify+0x954/0xd4c\n rtnl_dellink+0x210/0x530\n rtnetlink_rcv_msg+0x434/0x4d0\n netlink_rcv_skb+0xc4/0x204\n rtnetlink_rcv+0x18/0x24\n netlink_unicast+0x4b8/0x548\n netlink_sendmsg+0x29c/0x560\n ____sys_sendmsg+0x390/0x3ec\n ___sys_sendmsg+0x114/0x188\n __sys_sendmsg+0xf0/0x178\n __arm64_sys_sendmsg+0x48/0x60\n invoke_syscall.constprop.0+0x58/0x180\n el0_svc_common.constprop.0+0x74/0x140\n do_el0_svc+0x30/0x40\n el0_svc+0x38/0x98\n el0t_64_sync_handler+0xa0/0xe4\n el0t_64_sync+0x198/0x19c","Type":"Description","Title":"vxlan: mdb: Fix use-after-free in vxlan_mdb_flush()"}]}}}
