CVE-2023-47889Public exploit

Device shutdown and reboot via unprotected receivers

Published Feb 6, 2024 · Updated Jun 20, 2025

Improper intent verification in BINHDRM26 Super Reboot 1.0.3 allows local users to shut down or reboot Android devices. The exported PowerOffWidgetReceiver accepts an unprotected POWER_OFF broadcast without authenticating its sender, while other exported receivers expose recovery, bootloader, safe-mode, and process-restart actions. A malicious application installed on the same device can invoke these actions without user interaction, interrupting availability and potentially causing data loss.
