      "title": "net: vxlan: fix nd_tbl NULL dereference when IPv6 is disabled",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: vxlan: fix nd_tbl NULL dereference when IPv6 is disabled\n\nWhen booting with the 'ipv6.disable=1' parameter, the nd_tbl is never\ninitialized because inet6_init() exits before ndisc_init() is called\nwhich initializes it. If an IPv6 packet is injected into the interface,\nroute_shortcircuit() is called and a NULL pointer dereference happens on\nneigh_lookup().\n\n BUG: kernel NULL pointer dereference, address: 0000000000000380\n Oops: Oops: 0000 [#1] SMP NOPTI\n [...]\n RIP: 0010:neigh_lookup+0x20/0x270\n [...]\n Call Trace:\n  <TASK>\n  vxlan_xmit+0x638/0x1ef0 [vxlan]\n  dev_hard_start_xmit+0x9e/0x2e0\n  __dev_queue_xmit+0xbee/0x14e0\n  packet_sendmsg+0x116f/0x1930\n  __sys_sendto+0x1f5/0x200\n  __x64_sys_sendto+0x24/0x30\n  do_syscall_64+0x12f/0x1590\n  entry_SYSCALL_64_after_hwframe+0x76/0x7e\n\nFix this by adding an early check on route_shortcircuit() when protocol\nis ETH_P_IPV6. Note that ipv6_mod_enabled() cannot be used here because\nVXLAN can be built-in even when IPv6 is built as a module.",
