No, the temp swapspace is not encrypted. So we do have the vulnerability with intermediate shuffles. However, this is temporary short lived data and may not pose a major issue depending on the customer/usecase.

If this is still a concern, then put the temp swap space to a separate disk and encrypt the disk at OS Level
