gRPC-Go: Heap Memory Exhaustion (OOM) via HTTP/2 DATA Frame Fragmentation

Impact An unauthenticated remote attacker can initiate a gRPC stream and purposefully fragment their payload into millions of tiny e.g., 1-byte HTTP/2 DATA frames. Even if the total payload volume falls within the configured connection and stream flow-control windows, each independent fragment...
