Deck Mate 2's firmware update mechanism accepts packages without cryptographic signature verification, encrypts them with a single hard-coded AES key shared across devices, and uses a truncated HMAC for integrity validation. Attackers with access to the update interface - typically via the unit's USB update port - can craft or modify firmware packages to execute arbitrary code as root, allowing persistent compromise of the device's integrity and deck randomization process. Physical or on-premises access remains the most likely attack path, though network-exposed or telemetry-enabled deployments could theoretically allow remote exploitation if misconfigured. The vendor confirmed that firmware updates have been issued to correct these update-chain weaknesses and that USB update access has been disabled on affected units.

The CVE record on cve.org NVD's entry
The CVE record is authoritative. Products marked “from the name” were identified from the CNA's free-text names, not a CPE, and are matched less certainly. This product uses the NVD API but is not endorsed or certified by the NVD.
