Technical details
An out-of-bounds read vulnerability (CWE-125) exists in Silicon Labs EmberZNet v9.0.2 and earlier within the handling of the Zigbee 'Groups' cluster. A malformed 'GetGroupMembership' command can trigger repeated reads past the end of the message payload, leading to a process termination (denial-of-service). The attack requires the sender to be a device already authenticated and joined to the Zigbee network (PR:L). While the vulnerability involves an out-of-bounds read, no information leakage back to the attacker has been observed. Only devices supporting the Groups cluster are affected.
