Attacking NPUs of Multiple Platforms

...First, we will show the historical research background of the NPU security and attack surface. Next, we'll talk about the vulnerabilities that we found in different NPU systems, from Samsung Exynos, Qualcomm and Apple Silicon chipsets. We will then demonstrate the code auditing/firmware reversing methodology and bug patterns and we will discuss the code execution exploitation on Exynos NPU ARM core and Android root exploitation with a Qualcomm NPU kernel driver bug...
