Android Security Bulletin—January 2026

Published January 5, 2026

This Android Security Bulletin contains details of security vulnerabilities that affect Android devices. Security patch levels of 2026-01-05 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.

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.
