Overview
LLVM libFuzzer is a fuzzing tool referenced as a notable representative of modern Coverage-Guided Fuzzing (CGF), together with AFL. The cited GLSVLSI 2022 paper characterizes state-of-the-art fuzzing as using coverage-guided techniques that rely on mutation-based algorithms to generate new inputs, and identifies LLVM libFuzzer as part of that CGF category.
