CVE-2026-0716

A flaw was found in libsoups WebSocket frame processing when handling incoming messages. If a non-default configuration is used where the maximum incoming payload size is unset, the library may read memory outside the intended bounds. This can cause unintended memory exposure or a crash. Applications using libsoups WebSocket support with this configuration may be impacted.
