Abstract
In accordance with embodiments of the present disclosure, a compiler can compile source code to produce binary code that includes address shifting code inserted with memory operations. The address shifting code can shift addresses of memory operations that access locations in the kernel address space into address locations in the user space, thus avoiding speculative access into the kernel address space.
