CVE-2026-47148

In EmberZNet v9.0.2 and earlier, malformed GetGroupMembership commands can trigger repeated reads past the end of the message payload 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 Groups cluster may be impacted.
