CVE-2025-59408Public exploit

Firmware tampering via disabled Secure Boot

Published Sep 25, 2025 · Updated Sep 25, 2025

Missing Secure Boot in Flock Safety Bravo Edge AI Compute Device BRAVO_00.00_local_20241017 allows attackers to load modified firmware. Boot logs report Secure Boot as off, so the boot chain does not cryptographically reject a modified image written to UFS storage. Physical access to the circuit board or a flash cable is required to enter the demonstrated EDL workflow, after which altered firmware can run with root control.
