The present disclosure discloses a method and an apparatus for repairing a kernel vulnerability. A specific implementation of the method comprises: collecting attribute information of a to-be-repaired kernel, the attribute information comprising feature information for representing a code loading mode supported by the to-be-repaired kernel; acquiring a vulnerability repairing code matching the feature information, the vulnerability repairing code being used for invoking a patch application programming interface, the patch application programming interface being used for adapting the vulnerability repairing code to kernel functions of different kernels; loading the vulnerability repairing code and relocating an instruction contained in the vulnerability repairing code; replacing an address relocated by the patch application programming interface in the vulnerability repairing code with an address of the kernel function invoked by the vulnerability repairing code; and executing the vulnerability repairing code with the replaced address to repair the kernel vulnerability.
