In EmberZNet v9.0.2 and earlier, malformed or out-of-range Door Lock user identifiers can trigger out-of-bounds table reads and terminate the process. These messages must come from a device that has already joined the network, and no information leakage back to the sender was observed. Only devices supporting the Door Lock cluster may be impacted.
