CVE-2026-106428 is fixed in mongo-c-driver on 1 platform by DEBIAN-CVE-2026-106428 (version 2.4.0-1), released October 9, 2026. It is not reported as exploited. Patch Radar priority: Routine.
An out-of-bounds read in SCRAM authentication response parsing in the MongoDB C Driver can read one byte beyond a fixed-size buffer when processing a malformed server-final message. A server or network intermediary able to provide this message before server-signature verification can cause the application using the driver to terminate. The extra byte is not returned through the protocol.
