RUSTSEC-2026-0343 Outgoing datagram buffer accounting can panic the sender in quinn-proto

The limit on memory used to buffer outgoing datagrams, introduced in 0.11.17, subtracted an evicted datagram's size from the buffered byte counter twice when Datagrams::send was called with drop = true as Connection::senddatagram in the quinn crate does while the buffer was full. Under sustained...
