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

Disclosed are a vulnerability-fixing method and device. The method comprises: collecting attribute information about a kernel to be fixed (201), the attribute information comprising feature information used for characterizing a code-loading method supported by the kernel to be fixed; acquiring a vulnerability-fixing code matching the feature information (202); based on the attribute information, configuring the vulnerability-fixing code so that the vulnerability-fixing code is adapted to the kernel to be fixed (203); and using the configured vulnerability-fixing code to perform vulnerability fixing on the kernel to be fixed (204). This method is compatible with a plurality of methods for loading a kernel fixing code.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of information security technology, and in particular to a vulnerability repair method and device. Background technique [0002] Various security vulnerabilities are often found in the operating system kernel. Due to the complexity of the principle of the security vulnerability itself, it will consume a lot of human resources to deal with it. Some manufacturers will delay the update or even give up 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 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 t...
