Code execution via oversized Zigbee Model Info frame
Published Mar 13, 2026 · Updated Mar 13, 2026
Heap-based buffer overflow in Philips Hue Bridge 1.73.1973146020 allows physically proximate attackers to execute code via Zigbee pairing. The Model Info download handler copies attacker-controlled custom Zigbee ZCL frame data into a fixed-size heap buffer without validating its length. Exploitation requires the user to initiate device pairing, after which code runs in the device context.
