Abstract
A method and an apparatus for enhancing isolation of user space from kernel space, to divide an extended page table into a kernel-mode extended page table and a user-mode extended page table, such that user-mode code cannot access some or all content in the kernel space, and/or kernel-mode code cannot access some content in the user space, thereby enhancing isolation of the user space from the kernel space and preventing content leakage of the kernel space.
