CVE-2025-7964 describes a critical vulnerability in Zigbee networks where a malformed 802.15.4 MAC Data Request can cause a Zigbee Coordinator to send a "network leave" request to a Zigbee Router. This leaves the router in a non-rejoinable state, requiring manual recommissioning and potentially isolating end devices if no suitable parent is available. With a CVSS score of 9.2 (CRITICAL), this vulnerability has a network attack vector, low attack complexity, and high impact on availability, as it can render Zigbee Routers inoperable. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
