摘要

—There have been more vulnerabilities in the Linux kernel in 2013 than there had been in the previous decade. In this paper, the research was focused on defending against arbitrary memory overwrite in privilege escalation. To avoid malicious users getting root authority, the easiest way is to set the sensitive data structure to read-only. But we are not sure the sensitive data structure will never be modified by legal behavior from a normal device driver; thus, we posed an adaptive solution between read-only solutions and writable solutions which is based on the mechanism of read-only IDT table to enhance compatibility. The main idea that we posed not only solves the above problem, but also the general problem which is ensuring that important memory values can only be changed within a safe range. It is not just set to read-only. In addition, we do not need to care about if the Linux kernel exists any the vulnerabilities of arbitrary memory overwrite.
