+== "Smepmp" Extension for PMP Enhancements for memory access and execution prevention in Machine mode, Version 1.0
=== Introduction
Being able to access the memory of a process running at a high privileged execution mode, such as the Supervisor or Machine mode, from a lower privileged mode such as the User mode, introduces an obvious attack vector since it allows for an attacker to perform privilege escalation, and tamper with the code and/or data of that process. A less obvious attack vector exists when the reverse happens, in which case an attacker instead of tampering with code and/or data that belong to a high-privileged process, can tamper with the memory of an unprivileged / less-privileged process and trick the high-privileged process to use or execute it.
