[Bug]: StandaloneMmPkg does not clear memory protections on unloaded images #1244
Description
Is there an existing issue for this?
- I have searched existing issues
Current Behavior
In StandaloneMmPkg when a binary is loaded it's code sections will be marked with the read-only memory protections. If this image then fails, it will be unloaded and its memory reclaimed. However, the core does not unset the read-only attribute and if that address is re-used later it will cause an access violation when attempting to write to the memory still marked as read-only.
Expected Behavior
The memory should be restored to the default RW so future allocations of that memory are consistent with other memory allocations.
