| |
| <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. |
