CWE-229Published: January 30, 2026· Updated: Jun 17, 2026
Official Description
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.
Risk Analysis
Zigbee Coordinators are vulnerable to a denial-of-service attack where a malformed 802.15.4 MAC Data Request forces a router into a non-rejoinable state. This critical issue has a CVSS score of 9.2.
No public exploit is known, and it is not in the KEV. The vulnerability is remotely exploitable with low complexity.
Apply vendor-supplied firmware updates to handle malformed packets correctly or perform manual recommissioning as a temporary workaround.
Technical Analysis
CVE-2025-7964 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
