GrapheneOS Releases Alpha Build 2026090700 With Fixes and Security Updates
The new GrapheneOS 2026090700 build is currently available only in the Alpha channel. It fixes Private Space, updates hardened_malloc, and includes an extensive list of security fixes.
GrapheneOS Alpha build 2026090700 was released on September 7, 2026. The security-focused operating system has so far made it available exclusively through the Alpha testing channel, while the Beta and Stable channels for supported devices continue to list version 2026081300.
The release addresses a specific issue in Private Space for secondary users. When searching there, the prompt text for entering credentials could disappear. The build also updates the libdivide library used in hardened_malloc to version 5.4.0.
What GrapheneOS Alpha build 2026090700 brings
Alongside the functional fix and hardened_malloc component update, the project lists an extensive set of fixed CVE vulnerabilities, including items rated critical. The announcement also links to a separate security preview labeled 2026090701.
However, the available information does not make it possible to determine the impact of individual CVEs on specific supported Pixel models. GrapheneOS also has not confirmed that any of the fixed vulnerabilities are being actively exploited.
Stable and Beta channels do not have the new version yet
The update is already available to Alpha channel users. However, most GrapheneOS users use the Stable channel, where the new build has not yet been deployed. The same applies to the Beta channel.
Deployment to the Alpha channel allows the project to verify changes before a wider release. The timeline for version 2026090700, security preview 2026090701, or a possible newer replacement build to reach the Beta and Stable channels has not been announced.
What to watch next
- the new build or its replacement moving to the Beta and Stable channels,
- any additional security advisories with details about affected components and devices,
- confirmation that any of the fixed vulnerabilities are being actively exploited.
Device owners in the Alpha channel can check for the update in system settings. Stable channel users will have to wait for the fixes to become available in their branch.
