Exploring Fuzzing for Zephyr Applications with libFuzzer and AFL++

Open Source Summit North America 2026 and Embedded Linux Conference brought together the open source community in Minneapolis from May 18-20, 2026. As part of the Zephyr track, Jayashree Srinivasan from Analog Devices presented “Fuzzing Zephyr Apps: Struggles of Dynamic Analysis on Embedded Applications.” Fuzzing is a runtime testing technique that provides malformed, random, or unexpected inputs to software and monitors it for crashes, memory leaks, or other unexpected behaviour. Unlike static analysis, fuzzing only tests executed code paths, but it usually produces fewer false positives and
