Problems solved by technology

For traditional memory corruption vulnerabilities, the vulnerability itself will affect the normal operation of the system. Tools such as a verifier can be used to capture such anomalies more conveniently, but information leakage vulnerabilities will not trigger anomalies. Nor do they interfere with the proper functioning of the system, which makes finding them more difficult

Abstract

The invention discloses a kernel vulnerability discovery method and device, computing equipment and a computer storage medium. The kernel vulnerability discovery method includes the steps that operation of writing data in a user state memory by a kernel is monitored, and log information related with the operation of writing the data is acquired; the log information is analyzed, and an occurrence point of a kernel vulnerability is found out; readable information of the occurrence point of the kernel vulnerability is generated. According to the scheme, the leakage position, namely the occurrence point of the kernel vulnerability, of kernel information can be found out by analyzing the log information related with the operation of writing the data in the user state memory by the kernel, the vulnerability where the kernel information leaks can be easily, conveniently and efficiently found out in the mode, and following restoration is convenient.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a kernel vulnerability mining method, device, computing device and computer storage medium. Background technique [0002] The kernel is the core of an operating system and is also the first layer of software expansion based on hardware. It provides the most basic functions of the operating system and is the basis for the operation of the operating system. At the same time, kernel information leakage means that key information in the kernel may be used by exploiters to attack the system and other operations. [0003] Existing technologies have some mitigation measures for this type of kernel information leakage vulnerability: after the Windows Vista operating system, Microsoft introduced an address space configuration random loading technology (Kernel Address Space Layout Randomization, hereinafter referred to as KASLR) to the kernel, and KASLR randomized the ...
