Abstract

The rise of smart devices in critical domains—including automotive, medical, industrial—demands robust firmware testing. Fuzzing firmware in re-hosted environments is a promising method for automated testing at scale, but remains difficult due to the tight coupling of code with a microcontroller’s peripherals. Existing fuzzing frameworks primarily address input challenges in providing inputs for Memory-Mapped I/O or interrupts, but largely overlook Direct Memory Access (DMA), a key high-throughput interface used that bypasses the CPU.
