Abstract

A method and an apparatus for repairing a kernel vulnerability are disclosed. One embodiment of the method includes: collecting attribute information of a kernel to be repaired, the attribute information including characteristic information; obtaining vulnerability repair code that matches the characteristic information; acquiring metadata information describing the kernel to be repaired; relocating the instruction contained in the vulnerability repair code according to the metadata information, and then loading the vulnerability repair code; replacing the address of the patch API relocated inthe vulnerability repair code with the address of the kernel function called by the vulnerability repair code; executing the address replacement vulnerability repair code to fix the kernel vulnerability. This embodiment extends the use of vulnerability repair code to apply to multiple types of kernels.

Description

[0001] Cross References to Related Applications [0002] This application is a divisional application of a Chinese patent application with an application date of December 12, 2016, an application number of 201611139292.2, and an invention title of "Method and Device for Repairing Kernel Vulnerabilities". technical field [0003] The present application relates to the field of computer technology, specifically to the field of information security technology, and in particular to a method and device for repairing kernel vulnerabilities. Background technique [0004] The kernel is the core of the operating system, responsible for managing the system's processes, memory, device drivers, files and network systems, etc., and determines the performance and stability of the system. Since the method of replacing the kernel and restarting the system can not meet the high reliability requirements, there is a need for a vulnerability repair code technology that can immediately upgrade t...
