"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntipc: Check the bearer type before calling tipc_udp_nl_bearer_add()\n\nsyzbot reported the following general protection fault [1]:\n\ngeneral protection fault, probably for non-canonical address 0xdffffc0000000010: 0000 [#1] PREEMPT SMP KASAN\nKASAN: null-ptr-deref in range [0x0000000000000080-0x0000000000000087]\n...\nRIP: 0010:tipc_udp_is_known_peer+0x9c/0x250 net/tipc/udp_media.c:291\n...\nCall Trace:\n <TASK>\n tipc_udp_nl_bearer_add+0x212/0x2f0 net/tipc/udp_media.c:646\n tipc_nl_bearer_add+0x21e/0x360 net/tipc/bearer.c:1089\n genl_family_rcv_msg_doit+0x1fc/0x2e0 net/netlink/genetlink.c:972\n genl_family_rcv_msg net/netlink/genetlink.c:1052 [inline]\n genl_rcv_msg+0x561/0x800 net/netlink/genetlink.c:1067\n netlink_rcv_skb+0x16b/0x440 net/netlink/af_netlink.c:2544\n genl_rcv+0x28/0x40 net/netlink/genetlink.c:1076\n netlink_unicast_kernel net/netlink/af_netlink.c:1341 [inline]\n netlink_unicast+0x53b/0x810 net/netlink/af_netlink.c:1367\n netlink_sendmsg+0x8b7/0xd70 net/netlink/af_netlink.c:1909\n sock_sendmsg_nosec net/socket.c:730 [inline]\n __sock_sendmsg+0xd5/0x180 net/socket.c:745\n ____sys_sendmsg+0x6ac/0x940 net/socket.c:2584\n ___sys_sendmsg+0x135/0x1d0 net/socket.c:2638\n __sys_sendmsg+0x117/0x1e0 net/socket.c:2667\n do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n do_syscall_64+0x40/0x110 arch/x86/entry/common.c:83\n entry_SYSCALL_64_after_hwframe+0x63/0x6b\n\nThe cause of this issue is that when tipc_nl_bearer_add() is called with\nthe TIPC_NLA_BEARER_UDP_OPTS attribute, tipc_udp_nl_bearer_add() is called\neven if the bearer is not UDP.\n\ntipc_udp_is_known_peer() called by tipc_udp_nl_bearer_add() assumes that\nthe media_ptr field of the tipc_bearer has an udp_bearer type object, so\nthe function goes crazy for non-UDP bearers.\n\nThis patch fixes the issue by checking the bearer type before calling\ntipc_udp_nl_bearer_add() in tipc_nl_bearer_add()."
