CVE-2026-25800

A flaw was found in Quinn, a Rust implementation of the QUIC transport protocol. A remote attacker can exploit this vulnerability by sending specially crafted QUIC stream fragments with many gaps. This can lead to high buffer overhead in the Assembler component, causing memory exhaustion and a...

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...
