Voltage Glitching Attack Bypasses Safety Checks in PX4 Autopilot Flight Controllers
Researchers demonstrated a voltage-glitching attack against the PX4 Autopilot running on an STM32 microcontroller, enabling the bypassing of safety checks and the skipping of control instructions within the flight controller. The attack was shown on a flight controller board widely used across research, hobbyist, and commercial UAV applications, though the current implementation requires physical access to the device. Defenders should treat physical access to UAV flight controllers as a meaningful risk vector and evaluate hardware-level mitigations for STM32-based PX4 deployments.
