Machine-written summary

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

The quic-go package for Go, versions before 0.48.2, is affected. An off-path attacker who knows the client's IP address and port can inject an ICMP Packet Too Large message, causing the kernel to report "message too large" errors when quic-go sends packets. This can disrupt an established QUIC connection, even after the handshake. Upgrade to version 0.48.2 or later. Dropping ICMP Unreachable packets with iptables is a possible workaround.
