      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\npfcp: fix socket lifetime on netdevice registration failure\n\npfcp_newlink() creates the UDP socket before register_netdevice().\nIf registration fails after pfcp_dev_init() succeeds, the core calls\npfcp_dev_uninit(), which releases the socket and clears pfcp->sk.\nThe newlink error path then releases it again, causing a NULL pointer\ndereference. This was observed with failslab fault injection:\n\n  FAULT_INJECTION: forcing a failure.\n  kobject: kobject_add_internal failed for pfcp0 (error: -12 parent: net)\n  BUG: KASAN: null-ptr-deref in udp_tunnel_sock_release+0x1c/0x50\n  Read of size 8 at addr 0000000000000120 by task ip/1037\n  Call trace:\n   show_stack+0x18/0x24 (C)\n   dump_stack_lvl+0x78/0x90\n   print_report+0x468/0x5cc\n   kasan_report+0xa4/0xf0\n   __asan_load8+0x7c/0xd0\n   udp_tunnel_sock_release+0x1c/0x50\n   pfcp_newlink+0x128/0x184\n   rtnl_newlink+0x848/0xe44\n   rtnetlink_rcv_msg+0x468/0x514\n   netlink_rcv_skb+0xc0/0x1f0\n   rtnetlink_rcv+0x18/0x24\n   netlink_unicast+0x4b8/0x558\n   netlink_sendmsg+0x2b8/0x584\n   ...\n\nReturn from pfcp_del_sock() if pfcp->sk is NULL.",
