Local privilege bypass via undisclosed ADB flaw
Published Dec 24, 2025 · Updated Dec 24, 2025
Privilege bypass in ADB in HONOR MagicOS before 9.0.0.169 allows local users to cross an ADB privilege boundary with user interaction. HONOR has not disclosed the affected ADB code path or the incorrect privilege operation performed on attacker-controlled input. Exploitation requires low-privileged local access and high-complexity conditions; the vendor reports a service-availability effect but does not identify whether the service hangs, crashes, or restarts.
