Labels: ReleaseBlock-Stable
This is a serious security regression. If you are not able to fix this quickly, please revert the change that introduced it.

If this doesn't affect a release branch, or has not been properly classified for severity, please update the Security_Impact or Security_Severity labels, and remove the ReleaseBlock label. To disable this altogether, apply ReleaseBlock-NA.

+awhalley@ (Security TPM). Please note fix for this bug is not available yet and we already cut M67 stable RC.

vmpstr is out until mid-summer. This looks like it might be Security-Impact:None in Test-only code.

Removing this from the security queue since it appears to be test only.
