 <strong>2. What do the entries in the <em>Type</em> column mean?</strong>
 </p>
 <p>
 Entries in the <em>Type</em> column of the vulnerability details table reference
 the classification of the security vulnerability.

 </p>
 <p>
 Issues that are not publicly available have an * next to the Android bug ID in
 the <em>References</em> column. The update for that issue is generally contained
 in the latest binary drivers for Pixel devices available
 from the <a href="https://developers.google.com/android/drivers"
