With nexthop compatibility mode enabled,\na concurrent replacement can grow the group between these independent\nsnapshots.  rt6_fill_node() can then legitimately return -EMSGSIZE, so\nthe warning does not prove a sizing bug.\n\nRemove the warning.  The existing error path still frees the skb and\nreports the error to listeners.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/291fe0bafee78c95f9f2e7f579f17793fd5a1e5a","tags":[]},{"url":"https://git.kernel.org/stable/c/4ac7d92a4698e34e614c254359665b9de1f65283","tags":[]},{"url":"https://git.kernel.org/stable/c/7b112bd43f1172fb152e848570a957467008a5ae","tags":[]},{"url":"https://git.kernel.org/stable/c/8a3b935b6b6037eefb36bd27a60793a008358e8d","tags":[]},{"url":"https://git.kernel.org/stable/c/c97426ec649d99596d8969e1a052c16b14b7b485","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
