+<p>
+The Pixel&hairsp;/&hairsp;Nexus Security Bulletin contains details of security
+vulnerabilities and functional improvements affecting
+<a href="https://support.google.com/pixelphone/answer/4457705#pixel_phones&nexus_devices">supported
+Google Pixel and Nexus devices</a> (Google devices). For Google devices,
+security patch levels of 2018-04-05 or later address all issues in this
+bulletin and all issues in the <a href="/security/bulletin/2018-04-01">April
+2018 Android Security Bulletin</a>. To learn how to check a device's security
+patch level, see <a href="https://support.google.com/pixelphone/answer/4457705">Check
+and update your Android version</a>.</p>
+<p>
+All supported Google devices will receive an update to the 2018-04-05 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/nexus/images">Google Developer
+site</a>.
+</p>
+
+<h2 id="announcements">Announcements</h2>
+<p>In addition to the security vulnerabilities described in the
+<a href="/security/bulletin/2018-04-01">April 2018 Android Security Bulletin</a>,
+Google 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 that 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="https://source.android.com/security/overview/updates-resources.html#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,
+like the AOSP change list. When multiple changes relate to a single bug,
+additional references are linked to numbers following the bug ID.

+<h2 id="common-questions-and-answers">Common questions and answers</h2>
+<p>
+This section answers common questions that may occur after reading this
+bulletin.
+</p>
+<p>
+<strong>1. How do I determine if my device is updated to address these issues?
+</strong>
+</p>
+<p>
+Security patch levels of 2018-04-05 or later address all issues associated with
+the 2018-04-05 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">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>
+ <tr>

+ <td>Denial of service</td>
+ </tr>
+ <tr>
+ <td>N/A</td>
+ <td>Classification not available</td>
+ </tr>
+</table>
+<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>
+<table>
+ <col width="25%">
+ <col width="75%">

+ <tr>
+ <td>N-</td>
+ <td>NVIDIA reference number</td>
+ </tr>
+ <tr>
+ <td>B-</td>
+ <td>Broadcom reference number</td>
+ </tr>
+</table>
+<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 Nexus devices available from the
+<a href="https://developers.google.com/android/nexus/drivers">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 in order 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.
