Kernel resources and system calls are identified through static analysis, and a system call dependency graph is constructed. The data competition pair set and the system call dependency graph are used to guide the generation and mutation of kernel fuzzy test cases. A thread-aware fuzzy test generator is used to randomize the priority of threads to explore thread interleaving, and runtime feedback information is used to update the edge weights of the dependency graph, improve the system call dependency graph, and guide the mutation of subsequent fuzzy test inputs.
