Description

In EmberZNet v9.0.2 and earlier, a malformed GetProfileResponse message can trigger out-of-bounds reads while iterating interval entries 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 Simple Metering cluster may be impacted.
