CVE-2026-0716
Estado: AplazadaMedia (4.8)—
A flaw was found in libsoup’s 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 libsoup’s WebSocket support with this configuration may be impacted.
