Fuzzing Zephyr Apps - Struggles of Dynamic Analysis on Embedded Applications - Jayashree Srinivasan
The video presents Jayashree Srinivasan’s deep dive into fuzzing Zephyr‑based embedded applications, outlining why dynamic analysis is essential for safety‑critical IoT devices. She explains core concepts of fuzzing—randomized input injection, coverage collection, crash detection—and contrasts it with static analysis, noting lower false‑positive rates and ability to expose runtime faults such as buffer overflows in real‑time loops. Srinivasan cites concrete bugs discovered in Zephyr drivers (e.g., unchecked packet length leading to underflow) and highlights research tools like the LIP fuzzer integrated into LLVM, as well as rehosting frameworks (QEMU, Simics) and hardware‑in‑loop loops that emulate peripheral registers. The discussion underscores that building a faithful execution environment is the primary bottleneck; hybrid strategies that blend hardware‑in‑loop testing with high‑fidelity emulation can scale fuzzing across diverse MCU families, accelerating vulnerability discovery for manufacturers and regulators.
