| CVE ID | Severity | Description | Mitigation in V3.06 | | :--- | :--- | :--- | :--- | | | High (8.2) | Unrestricted upload of dangerous file types via web configuration interface. | Implemented MIME type whitelisting and scan engine. | | CVE-2024-11034 | Critical (9.1) | Use of hard-coded cryptographic key in the firmware update mechanism. | Replaced static key with per-device TPM-derived ephemeral key. | Mtcc-kld6-v3.06 Update

The MTCC-KLD6-v3.06 update delivers substantial improvements in real-time determinism, high-throughput IPC, and hardware-enforced security without breaking existing ABI. Production users of v3.05 in latency-sensitive or security-critical environments are strongly encouraged to upgrade. The kernel continues to serve as a reference platform for mixed-criticality systems requiring both performance and verifiability. | Implemented MIME type whitelisting and scan engine

Before flashing any files, verify your and MCU Version in the "About Device" section of your settings. MTCC units are a specific evolution of the MTCB/MTCD family; installing firmware meant for a different board can "brick" the unit, rendering it a paperweight. Always ensure the update file is specifically labeled for the KLD (Klyde) manufacturer prefix. The Installation Process | The MTCC-KLD6-v3

The KLD6 is renowned for its dual-core lockstep architecture and support for legacy Modbus RTU alongside modern OPC UA. The V3.06 update specifically targets the firmware of the Communications Co-Processor (CCP) and the Kernel Logic Driver (KLD) sub-system.
