Android Security Bulletin—April 2026

Published April 6, 2026

This Android Security Bulletin contains details of security vulnerabilities that affect Android devices. Security patch levels of 2026-04-05 or later address all of these issues. To learn how to check a device's security patch level, see Check and update your Android version.

Within 48 hours after the initial publication of this bulletin, we will release the corresponding source code patches to the Android Open Source Project (AOSP) repository. We will then revise this bulletin with the AOSP links.

The most severe of these issues is a critical security vulnerability in the Framework component that could lead to local denial of service with no additional execution privileges needed. User interaction is not needed for exploitation. The severity assessment is 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.

For more details on the Android security platform protections and Google Play Protect, which improve the security of the Android platform, refer to the Android and Google Play Protect mitigations section.

We notify our Android partners of all issues at least a month before publishing the bulletin.

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.
