CVE-2026-94450 - Potential denial of service when configured to send Retry packets in s2n-quic
Bulletin ID: 2026-116-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 09/22/2026 13:00 PM PDT Description: s2n-quic is a Rust implementation of the QUIC protocol. We identified CVE-2026-94450, an issue with improper validation of the Destination Connection ID length when a server is configured to send Retry packets. s2n-quic 1.88.0 and earlier allow an unauthenticated user to shut down a server endpoint via a single crafted UDP datagram. No AWS services are affected by this issue, and customers of AWS services do not need to take action. Only server endpoints specifically configured to issue Retry packets are affected. Impacted versions: <= v1.88.0 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
