CVE-2022-47100Public exploit

Factory reset via crafted wireless frame

Published Jan 24, 2023 · Updated Apr 2, 2025

Improper input validation in Sengled Smart bulb firmware 0x0000024 allows physically proximate attackers to factory-reset the device. The public report demonstrates the reset with a crafted IEEE 802.15.4 frame but does not identify the firmware function that misprocesses it. Radio range is required; the reset erases device configuration and interrupts normal bulb control.
