The\nRTA_OIF arm passes tb[RTA_OIF] to nla_get_u32() without checking it is\npresent, so an RTM_GETROUTE dump for AF_MPLS with strict checking and no\nRTA_OIF hits a NULL dereference.\n\nRTM_GETROUTE is RTNL_KIND_GET, which rtnetlink_rcv_msg() permits without\nCAP_NET_ADMIN, so an unprivileged user can trigger it.\n\n Oops: general protection fault, probably for non-canonical address\n 0xdffffc0000000000: 0000 [#1] SMP KASAN NOPTI\n KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]\n RIP: 0010:mpls_valid_fib_dump_req (net/mpls/af_mpls.c:2189)\n Call Trace:\n mpls_dump_routes (net/mpls/af_mpls.c:2236)\n netlink_dump (net/netlink/af_netlink.c:2331)\n __netlink_dump_start (net/netlink/af_netlink.c:2446)\n rtnetlink_rcv_msg (net/core/rtnetlink.c:7033)\n netlink_rcv_skb (net/netlink/af_netlink.c:2556)\n netlink_unicast (net/netlink/af_netlink.c:1345)\n netlink_sendmsg (net/netlink/af_netlink.c:1900)\n __sock_sendmsg (net/socket.c:790)\n ____sys_sendmsg (net/socket.c:2684)\n ___sys_sendmsg (net/socket.c:2738)\n __sys_sendmsg (net/socket.c:2770)\n do_syscall_64 (arch/x86/entry/syscall_64.c:94)\n entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:121)\n\nSkip unset attributes, as ip_valid_fib_dump_req() does."
