After receiving a malformed 802.15.4 MAC Data Request the Zigbee Coordinator sends a ‘network leave’ request to Zigbee router resulting in the Zigbee Router getting stuck in a non-rejoinable state. If a suitable parent is not available, the end devices will be unable to rejoin. A manual recommissioning is required to recover the Zigbee Router.
