Approaches to determining the attack surface for fuzzing the Linux kernel

Abstract

The purpose of the study was to analyze possible methods for determining the attack surface in relation to solving the problem of fuzzing testing the kernel of operating systems of the Linux family and to select the most suitable one. To evaluate and compare various models and practical approaches to attack surface analysis, as well as assess the possibility of combining them, theoretical research methods such as analysis, comparison, and deduction were used. An assessment and comparison of existing models and approaches to analyzing the attack surface of the Linux operating system kernel was carried out. A solution is proposed for the practical determination of the attack surface for effective testing of the kernel using the fuzzing method, which combines the studied approaches. The results of the study can be used to practically construct an attack surface, which will allow us to more accurately determine the goals of fuzz testing of the Linux kernel.
