NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup3-doc package and not the libsoup3-doc package as distributed by AlmaLinux. See How to fix? for AlmaLinux:10 relevant fixed versions and status.

A flaw was found in libsoup. When handling an incoming WebSocket Pong frame, SoupWebsocketConnection emitted the ::pong signal with a GByteArray pointer even though the signal is declared to pass a GBytes. Applications connecting a handler that follows the documented GBytes API can trigger heap corruption or a crash upon receiving a crafted Pong.
