"value": "In the Linux kernel, the following vulnerability has been resolved:\n\novpn: replace bind when clearing stale local source\n\nThe UDP output fallback clears bind->local in place when the remembered\nsource address is no longer usable. The bind is RCU-published and read\nlocklessly by concurrent TX, so an IPv6 reader can observe a torn\naddress.\n\nRetry the route lookup with source address autoselection without\nmodifying the bind. After a successful lookup, revalidate the bind and\nroute key under peer->lock, reset the dst cache, and best-effort publish\na replacement bind with a wildcard local address.\n\nDo not cache the resolved dst when clearing the local source. Replacing\nthe source invalidates all per-CPU cache entries, while\ndst_cache_set_ip4 and dst_cache_set_ip6 update only the current CPU\nslot. The current packet can still use the resolved route; if bind\nallocation fails, a later cache miss retries the repair."
