What is the change? - PXN attributes is set for static mpu regions such that __ramfunc and __ram_text_reloc having userspace code cannot be executed in privileged mode. - Updated the notable change section to inform about the change in behaviour of code executed from __ramfunc and __ram_text_reloc MPU regions. Why do we need this change? - The current static MPU regions allows executing userspace/unprivileged code from privileged mode which may not be expected and can lead to secure privileged escalation attacks.
