CVE-2026-33814 is an infinite-loop vulnerability in an HTTP/2 transport implementation. When the transport processes a peer SETTINGS frame that sets SETTINGS_MAX_FRAME_SIZE to zero, it can repeatedly write HTTP/2 CONTINUATION frames without making progress. The malformed but attacker-controlled SETTINGS value therefore causes non-terminating frame-generation behavior.
