Abstract

The application discloses a method and a device for repairing kernel vulnerabilities. A specific implementation of the method includes: collecting attribute information of the kernel to be repaired, and the attribute information includes characteristic information used to characterize the code loading mode supported by the kernel to be repaired; obtaining the vulnerability repair code matching the characteristic information, wherein the vulnerability repair code Used to call the patch application programming interface, the patch application programming interface is used to adapt the vulnerability repair code to the kernel function of different kernels; load the vulnerability repair code and relocate the instructions contained in the vulnerability repair code; The address after the relocation of the patch application programming interface is replaced with the address of the kernel function called by the vulnerability repair code; the vulnerability repair code after the address replacement is executed to repair the kernel vulnerability. This implementation manner expands the use range of the vulnerability repair code, so that it can be applied to various types of kernels.

Description

Technical field [0001] This application relates to the field of computer technology, in particular to the field of information security technology, and in particular to a method and device for repairing kernel vulnerabilities. Background technique [0002] The kernel is the core of the operating system, responsible for managing the system's processes, memory, device drivers, files, and network systems, and determines the performance and stability of the system. Because the kernel vulnerability repair code method of replacing the kernel and restarting the system cannot meet the high reliability requirements, a vulnerability repair code technology that supports the function of the kernel to be repaired can be upgraded immediately during the operation of the kernel. The existing kernel hot vulnerability repair code technology repairs kernel functions in the form of memory vulnerability repair code during the kernel running process without replacing the entire kernel, which is benefi...
