rust-yamux: Yamux is a stream multiplexer over reliable, ordered connections such as TCP/IP
CVE-2026-32314 is fixed in rust-yamux on 1 platform by DEBIAN-CVE-2026-32314 (version 0.13.10+ds-1), released March 16, 2026. It is not reported as exploited. Patch Radar priority: High.
Yamux is a stream multiplexer over reliable, ordered connections such as TCP/IP. Prior to 0.13.10, the Rust implementation of Yamux can panic when processing a crafted inbound Data frame that sets SYN and uses a body length greater than DEFAULT_CREDIT (e.g. 262145). On the first packet of a new inbound stream, stream state is created and a receiver is queued before oversized-body validation completes. When validation fails, the temporary stream is dropped and cleanup may call remove(...).expect("stream not found"), triggering a panic in the connection state machine. This is remotely reachable over a normal Yamux session and does not require authentication. This vulnerability is fixed in 0.13.10.
