This is a longstanding issue that was just exposed recently, but the fix has evolved into a riskier change that needs a lot of testing. Released Linux shim versions with DebugClearMemory enabled will be broken when loading certain Linux payloads without this change (and there is a risk without DebugClearMemory enabled that pages would get allocated to the next caller of AllocatePages set to RO and cause unknown crashes). I defer to the stewards on the need to have this stable tag contain a fix for this case or for it to get more testing first (again, my preference).
