 class="external">supported Google Pixel and Nexus devices</a> (Google devices).
 For Google devices, security patch levels of 2018-11-05 or later address all
 issues in this bulletin and all issues in the November 2018 Android Security
 Bulletin. To learn how to check a device's security patch level, see <a
 href="https://support.google.com/pixelphone/answer/4457705"
 class="external">Check & update your Android version</a>.
 </p>
 <p>
 All supported Google devices will receive an update to the 2018-11-05 patch
 level. We encourage all customers to accept these updates to their devices.
 </p>
 <p class="note">
 <strong>Note:</strong> The Google device firmware images are available on the
 <a href="https://developers.google.com/android/images" class="external">Google
 Developer site</a>.
 </p>

 <h2 id="announcements">Announcements</h2>

 <p>In addition to the security vulnerabilities described in the
 <a href="/security/bulletin/2018-11-01">November 2018 Android Security
 Bulletin</a>, Pixel and Nexus devices also contain patches for the security
 vulnerabilities described below. Partners were notified of these issues at
 least a month ago and may choose to incorporate them as part of their device
 updates.
 </p>

 <h2 id="security-patches">Security patches</h2>
 <p>
 Vulnerabilities are grouped under the component they affect. There is a
 description of the issue and a table with the CVE, associated references,
 <a href="#type">type of vulnerability</a>,
 <a href="/security/overview/updates-resources#severity">severity</a>,
 and updated Android Open Source Project (AOSP) versions (where applicable).
 When available, we link the public change that addressed the issue to the bug
 ID, such as the AOSP change list. When multiple changes relate to a single bug,
 additional references are linked to numbers following the bug ID.

 </p>
 <p>
 <strong>1. How do I determine if my device is updated to address these issues?
 </strong>
 </p>
 <p>
 Security patch levels of 2018-11-05 or later address all issues associated with
 the 2018-11-05 security patch level and all previous patch levels. To learn how
 to check a device's security patch level, read the instructions on the <a
 href="https://support.google.com/pixelphone/answer/4457705#pixel_phones&nexus_devices"
 class="external">Pixel and Nexus update schedule</a>.
 </p>
 <p id="type">
 <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>
 <table>
   <col width="25%">
   <col width="75%">
   <tr>
    <th>Abbreviation</th>
    <th>Definition</th>
   </tr>

 <p>
 <strong>3. What do the entries in the <em>References</em> column mean?</strong>
 </p>
 <p>
 Entries under the <em>References</em> column of the vulnerability details table
 may contain a prefix identifying the organization to which the reference value
 belongs.

 <p id="asterisk">
 <strong>4. What does a * next to the Android bug ID in the <em>References</em>
 column mean?</strong>
 </p>
 <p>
 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&hairsp;/&hairsp;Nexus devices available
 from the <a href="https://developers.google.com/android/nexus/drivers"
 class="external">Google Developer site</a>.
 </p>
 <p>
 <strong>5. Why are security vulnerabilities split between this bulletin and the
 Android Security Bulletins?</strong>
 </p>
 <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.
