SUSE CVE-2026-25800

Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol. Starting in version 0.1.0 and prior to version 0.11.15, the Assembler component that assembles unordered stream fragments into consecutive chunks of the stream incurs some overhead for non-contiguous...

Quinn: Remote memory exhaustion in quinn-proto from unbounded out-of-order stream reassembly

Summary The Assembler component that assembles unordered stream fragments into consecutive chunks of the stream incurs some overhead for non-contiguous fragments. Readers that read from a RecvStream in order through an AsyncRead impl for example will be sensitive to peers that send fragments whil...

CVE-2026-25800

Quinn-quic: The Assembler handling unordered stream fragments can cause high memory overhead and potential memory exhaustion for non-contiguous fragments when reading RecvStream via AsyncRead, in versions 0.1.0 through 0.11.14. The issue arises from overhead in defragmentation of fragments with g...

GHSA-6XVM-J4WR-6V98 Quinn affected by unauthenticated remote DoS via panic in QUIC transport parameter parsing

Summary A remote, unauthenticated attacker can trigger a denial of service in applications using vulnerable quinn versions by sending a crafted QUIC Initial packet containing malformed quictransportparameters. In quinn-proto parsing logic, attacker-controlled varints are decoded with unwrap, so...

Quinn Input Validation Error Vulnerability

Quinn is a pure Rust, asynchronous-compliant implementation of the IETF QUIC transport protocol from the quinn-rs open source. An input validation error vulnerability exists in quinn-proto that stems from a Denial of Service DoS that occurs when an unknown frame is received in a QUIC packet...
