Summary
This research describes FirmLocator, a tool that automatically identifies the exact location of bugs in ARM embedded firmware (software running on embedded devices like microcontrollers) after fuzzing (automated testing that feeds random inputs to find crashes) discovers them. The tool uses memory tracking and data dependency analysis (tracing how information flows through code) to pinpoint the faulty instructions, achieving 98.3% accuracy in pinpointing bugs within the top 10 suspicious lines of code.
