Vulnerabilities in the device drivers of today's commodity operating systems (e.g., Android) remain a security concern due to the monolithic structure of the kernel. In this talk, we introduce three methods to mitigate this concern, with a focus on mobile devices. These approaches include a novel tool to find and analyze these vulnerabilities, an efficient vetting layer to make exploits harder, and a device driver design possible for I/O devices with virtualization support.
