Issues that are not publicly available have a * 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 / Nexus devices available
from the <a href="https://developers.google.com/android/drivers"

<p>
Security vulnerabilities that are documented in the Android Security Bulletins
are required to declare the latest security patch level on Android
devices. Additional security vulnerabilities, such as those documented in this
bulletin are not required for declaring a security patch level.
