Android 11 Security Release Notes

Published August 25, 2020

This Android Security Release Notes contains details of security vulnerabilities affecting Android devices which are addressed as part of Android 11. Android 11 devices with a security patch level of 2020-09-01 or later are protected against these issues (Android 11, as released on AOSP, will have a default security patch level of 2020-09-01). To learn how to check a device's security patch level, see Check and update your Android version.

Android partners are notified of all issues prior to publication. Source code patches for these issues will be released to the Android Open Source Project (AOSP) repository as part of the Android 11 release.

The severity assessment of issues in these release notes are based on the effect that exploiting the vulnerability would possibly have on an affected device, assuming the platform and service mitigations are turned off for development purposes or if successfully bypassed.

We have had no reports of active customer exploitation or abuse of these newly reported issues. Refer to the Android and Google Play Protect mitigations section for details on the Android security platform protections and Google Play Protect, which improve the security of the Android platform.


  • The issues described in this document are addressed as part of Android 11. This information is provided for reference and transparency.
  • We would like to acknowledge and thank the security research community for their continued contributions towards securing the Android ecosystem.

Android and Google Service Mitigations

This is a summary of the mitigations provided by the Android security platform and service protections such as Google Play Protect. These capabilities reduce the likelihood that security vulnerabilities could be successfully exploited on Android.

  • Exploitation for many issues on Android is made more difficult by enhancements in newer versions of the Android platform. We encourage all users to update to the latest version of Android where possible.
  • The Android security team actively monitors for abuse through Google Play Protect and warns users about Potentially Harmful Applications. Google Play Protect is enabled by default on devices with Google Mobile Services, and is especially important for users who install apps from outside of Google Play.
