CVE-2025-59404Public exploit

Partition modification via unlocked bootloader

Published Sep 25, 2025 · Updated Sep 25, 2025

Unlocked bootloader in Flock Safety Bravo Edge AI Compute Device BRAVO_00.00_local_20241017 allows attackers to modify partitions. The boot chain leaves the bootloader unlock state enabled, so partition changes are accepted without Android Verified Boot enforcing image integrity. Physical access to the unit and its USB-C interface is required; the demonstrated consequence is persistent firmware modification and a root shell.
