Summary
EmberZNet, the Zigbee networking software stack used in certain wireless devices, is affected by this flaw, which lets an attacker who has already joined the network crash devices that support the Group Cluster by sending a malformed GetGroupMembership message. The resulting denial of service can take those devices offline, though the out-of-bounds write was not found to enable remote code execution.

Read the original description
In EmberZNet 9.1.1 and earlier, a malformed GetGroupMembership message can result in an out-of-bounds write leading to a crash. A limited number of values can be written using this vulnerability, so no route to remote code execution was observed. These messages must come from a device that has already joined the network. Only devices supporting the Group Cluster are impacted.
