Filed: 2018-06-29
Abstract: Systems and methods that include kernel address detection circuitry to identify a current privilege level (CPL) of a speculatively executed instruction as either a kernel-level instruction or a user-level instruction are provided. For instructions identified as kernel-level, the kernel address detection circuitry permits access to all or a portion of both kernel memory space and user memory space within the system memory. For instructions identified as user-level, the kernel address detection circuitry permits access to all or a portion of the user memory space within the system memory. If a user-level instruction attempts to access a physical memory address within the defined kernel memory space, the kernel address detection circuitry generates an exception and does not provide the user-level instruction access to the physical address in the kernel memory space. Thus, the systems and methods prevent memory accesses used in side channel attacks such as Meltdown.
