  "title": "ipv6: do not warn on route notification size race",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  ipv6: do not warn on route notification size race  fib6_info_hw_flags_set() sizes the skb with rt6_nlmsg_size() and later fills it with rt6_fill_node().  With nexthop compatibility mode enabled, a concurrent replacement can grow the group between these independent snapshots.  rt6_fill_node() can then legitimately return -EMSGSIZE, so the warning does not prove a sizing bug.  Remove the warning.  The existing error path still frees the skb and reports the error to listeners.",
