"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nipv4: do not warn on route notification size race\n\nCommit 680aea08e78c (\"net: ipv4: Emit notification when fib hardware\nflags are changed\") added asynchronous route notifications for hardware\nflag changes.\n\nfib_alias_hw_flags_set() sizes the skb with fib_nlmsg_size() and later\nfills it with fib_dump_info() while holding only RCU. With nexthop\ncompatibility mode enabled, a concurrent replacement can grow the group\nbetween these independent snapshots. fib_dump_info() can then\nlegitimately return -EMSGSIZE, so the 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."
