The problem of insecure computing environments has large impacts on society: security breaches lead to violations of privacy, financial frauds, espionage, sabotage, lost productivity, and more. These, in turn, result in vast economic damage. A major reason for the severity of these consequences is that many systems run on top of an insecure operating system kernel. The Linux kernel, a de facto industry standard for embedded, mobile, cloud, and supercomputing environments, is often a target for security attacks.
