Problems solved by technology

Taking the Linux kernel as an example, the kernel versions used in various Android devices are characterized by fragmentation, and the differences between different kernels are large, so there is a lack of good code versatility. limit
[0003] Due to the above reasons, the repair methods in the prior art depend on the source code of the running system or require the original kernel to provide corresponding functions to cooperate, and the generated patch can only be used to repair a specific compiled version of the kernel, which is extremely limited. Its application scenarios and compatibility

Abstract

The invention discloses a bug fixing method and device. The method includes concrete implement modes that attribute information of a kernel to be fixed is collected and includes feature information used for representing the code loading mode supported by the kernel to be fixed; bug fixing codes matched with the feature information is obtained; based on the attribute information, the bug fixing codes are configured to fit the kernel to be fixed; the configured bug fixing codes are used for carrying out bug fixing on the kernel to be fixed. The execution mode is compatible with multiple kernel fixing code loading methods.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of information security technology, and in particular to a method and apparatus for repairing vulnerabilities. Background technique [0002] Various security vulnerabilities are often found in the operating system kernel. Due to the complexity of the security vulnerabilities themselves, a lot of human resources will be consumed to deal with them. Some manufacturers will delay the update or even abandon the maintenance of the old version, which brings great security risks to users. Taking the Linux kernel as an example, the kernel versions used in various Android devices are fragmented, and there are large differences between different kernels, so they lack good code versatility. The Linux kernel itself and manufacturers also set up some security mechanisms to load code. limit. [0003] Due to the above reasons, the repair method in the prior art relies on ...
