+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 2018-02-05 or later address all issues in this
+bulletin and all issues in the <a href="/security/bulletin/2018-02-01">February
+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 2018-02-05 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/2018-02-01">February 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 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.

+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 2018-02-05 or later address all issues associated with
+the 2018-02-05 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.

+<strong>3. What do the entries in the <em>References</em> column mean?</strong>

+<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.
