当在某个进程的上下文中执行以此模式运行的代码时，它不仅对全局内核地址空间具有读写访问权限，还将对该进程中的内核数据也具有读写访问权限。

Code operating in this mode has read and write access to the global kernel address space and kernel data in the process region when executing within the context of a process.

每个操作系统进程占用自己的虚拟地址空间，即一组可以读写的虚拟内存页。

Each operating-system process is allocated its own virtual address space — a set of virtual-memory pages that it can read from and write to. Each page can be in one of three states.

这意味着，你的程序访问(读写)一个内存地址，它没有权利。

That means that your program is accessing (either reading or writing) a memory address to which it does not have rights.
