CVE-2025-59402Public exploit

Physical firmware modification via unauthenticated Firehose loader

Published Sep 25, 2025 · Updated Sep 25, 2025

Authentication bypass in Flock Safety Bravo Edge AI Compute Device BRAVO_00.00_local_20241017 allows physically proximate attackers to flash firmware. In EDL/QDL mode, the device accepts the default Thundercomm TurboX 6490 Firehose loader without authenticating it, exposing raw UFS partition read and write operations. Physical access to the board and entry into EDL mode are required; the demonstrated procedure dumps partitions and writes modified boot images to obtain root control.
