Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

quic-go versions 0.37.0 before 0.37.3 are vulnerable to a nil pointer dereference that causes a panic. A remote attacker can trigger it by sending packets during the QUIC handshake, which can bring down the node. Upgrade to quic-go 0.37.3, which contains the fix.
