Abstract

The present invention discloses a kernel fixing method and apparatus. One specific embodiment of the method comprises loading a patch for fixing a to-be-fixed objective function in a kernel, wherein the patch is compiled by memory security language or memory security language subset of non-memory security language; executing the patch by using a memory security language engine; receiving and executing a call request for calling a fixing interface to fix the objective function during the patching process, wherein the fixing interface is provided by the memory security language engine and used for fixing the function; and executing the requested fixing interface to fix the objective function. Hot fixing and security of the kernel are achieved.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of information security, and in particular to a kernel repair method and device. Background technique [0002] Kernel vulnerabilities are a technical problem faced by Android devices. At present, although a large number of kernel vulnerabilities have been disclosed, there are still many Android devices that do not receive timely updates. The black industry can use these vulnerabilities to break through almost all security protection mechanisms such as encryption, fingerprints, and data isolation set in the device. Mobile phone manufacturers cannot concentrate on discovering and repairing kernel vulnerabilities like third-party manufacturers with security capabilities, so it is difficult to solve this problem only by relying on mobile phone manufacturers. In addition, the Android industry chain is very long, and it is too late for kernel patches to reach use...
