CVE-2026-31812

In Quinn (Rust, QUIC), the quinn-proto parsing path decodes attacker-controlled varints with unwrap(), so a crafted QUIC Initial packet containing malformed quic_transport_parameters can trigger an unexpected end and panic. This remote, unauthenticated DoS is reachable over the network and affect...
