CVE-2026-116014open62541 1.5.0 before 1.5.7 contains an integer overflow in UA_DataType_fromStructureDescription() that wraps the 16-bit memSize field for large custom structure definitions Executive summary An integer overflow in the open62541 OPC UA library affects versions 1.5.0 before 1.5.7 when it processes large custom structure definitions. The advisory describes the flaw as wrapping a 16-bit memory size field, but it does not state the severity or any CVSS score. The advisory does not say what the vendor recommends, though the affected version range implies that upgrading to 1.5.7 or later addresses it. Technical summary The flaw is an integer overflow in UA_DataType_fromStructureDescription() that wraps the 16-bit memSize field when a large custom structure definition is processed. The advisory does not state the attack vector, the preconditions for exploitation, or whether authentication is needed. The affected range is 1.5.0 before 1.5.7, and the fixed version is 1.5.7. The advisory does not state any workaround or detection guidance, and it does not state whether exploitation has been observed in the wild. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
