Technical details
An out-of-bounds write vulnerability exists in the GetGroupMembership message handler of the Group Cluster in EmberZNet 9.1.1 and earlier. The vulnerability requires an authenticated attacker on the Zigbee network to send a crafted message; the limited scope of values that can be written prevents remote code execution but enables denial-of-service through device crash. Watchdog mechanisms can detect and recover from these attacks.
