The Variable PEI and RuntimeDxe drivers were using the attribute 'HeaderLength' of EFI_FIRMWARE_VOLUME_HEADER without checking if a Firmware Volume Header was existing at the base address. In case the Firmware Volume Header does not exist or is corrupted, the attribute 'HeaderLength' is a non valid value that can lead to a non valid physical address when accessing produces an access error.
