No, or at least not yet. I mean, I've written plenty of bugs. More than I can count. How many of them were genuine security vulnerabilities if properly exploited? Probably not zero. But... I don't know. And I wrote the code!

Intel said it can be used for escalation if that answers your question.

Did they confirm that it can definitely be used for escalation? The description I saw was "may allow an authenticated user to potentially enable escalation of privilege and/or information disclosure and/or denial of service via local access" which sounds like they're covering all their bases and may not actually know what is and isn't possible.
