Gaurav Aggarwal 79704b8213 Remove local stack variable form MPU wrappers ... It was possible for a third party that had already independently gained the ability to execute injected code to achieve further privilege escalation by branching directly inside a FreeRTOS MPU API wrapper function with a manually crafted stack frame. This commit removes the local stack variable `xRunningPrivileged` so that a manually crafted stack frame cannot be used for privilege escalation by branching directly inside a FreeRTOS MPU API wrapper. We thank Certibit Consulting, LLC, Huazhong University of Science and Technology and the SecLab team at Northeastern University for reporting this issue.
