CVE-2026-102558

A heap buffer overflow vulnerability exists in libsoup within the SoupWebsocketConnection component. When the max-incoming-payload-size is set to unlimited (0), an attacker can provide a controlled frame length that causes the length to wrap during the growth of the incoming GByteArray . This res...
