    Abstract: Linux Kernel 的弱點數目在2013年達到高峰,更勝過去自1991年以來的弱點數目。本篇論文關注於Privilege Escalation攻擊類型中任意寫入memory的防禦方式。


    ;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 overwrites 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 a compatible solution between read-only solutions and writable solutions 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.
