Kanishk Bansal (@Kanishk-Bansal) Looks like the upstream PR has not been merged yet. Could you please monitor and re-add the ready for reviewer label once the fix is merged?

You could also reach out to Nikhil (from MSRC) to learn what the final fix is. In the comment section in the upstream PR, there seems to be an ongoing conversation on an alternative backport which suggests they have not fully agreed on the final fix.
