How to Better Fuzz Windows 10 Directx Kernel at Present

The presentation discusses new research on DirectX, including new attack methods and paths, and how to design targeted fuzz to find vulnerabilities. The speaker also explores how to better design closed source fuzz.

• DirectX architecture and system calls
• Discovery of new attack methods and paths
• Designing targeted fuzz to find vulnerabilities
• Exploring how to better design closed source fuzz

The speaker discusses how they discovered a system mechanism in DirectX that releases shared memory when a process is destroyed, and how this can be exploited to find vulnerabilities.

DirectX is the engine that handles rendering on the Windows platform. Many outstanding people have made outstanding contributions in the research of DirectX. In this talk, I will share new research content of DirectX including the discovery of new attack methods, new paths, and how to design targeted fuzz based on these, and find related vulnerabilities. I will also introduce the experience of designing Windows kernel fuzz and explore how to better design closed source fuzz.
