eBPF is widely used in Microsoft, Google, and Facebook because it is able to extend kernel without modifying the kernel source code. Nevertheless, vulnerabilities in kernel with eBPF will affect the stability and security of information system. Fuzzing has proven to be an effective approach for finding kernel bugs since it requires minimal knowledge about the target. However, two main challenges exist in discovering eBPF logical bugs: generating input that satisfies all eBPF instruction semantic requirements, and detecting the eBPF logical bug states. We remove highly semantically demanding and unnecessary instructions by analyzing the impact of the instructions to obtain a higher verification pass rate to address the first challenge. We also develop a bound-violation indicator to address the second challenge based on our analysis of eBPF logical bug patterns. We manually introduce 10 recently fixed logical bugs in eBPF for evaluation, and the experimental results show that we can effectively find 9 of them, while Syzkaller fails on all of them. In addition, 4 new bugs have been fixed for upstream Linux based on our work, and 3 functional issues have been reported.
