By serializing an ACK frame after the CRYTPO that allows a node to complete the handshake, a remote node could trigger a nil pointer dereference (leading to a panic) when the node attempted to drop the Handshake packet number space.\n\n**Impact**\n\nAn attacker can bring down a quic-go node with very minimal effort. Completing the QUIC handshake only requires sending and receiving a few packets.\n\n**Patches**\n\n[v0.37.3](https://github.com/quic-go/quic-go/releases/tag/v0.37.3) contains a patch.
