CVE-2025-1704 Overview
CVE-2025-1704 affects Google ChromeOS version 15823.23.0 running on Chromebook devices. The vulnerability resides in the ComponentInstaller mechanism, which loads components from the unencrypted stateful partition. Enrolled users with local access can modify these components to unenroll managed devices and intercept device management requests. This breaks the trust boundary between the device owner and the enterprise management infrastructure. The flaw is categorized under [CWE-416] Use After Free in the reference data and impacts device integrity guarantees expected in managed ChromeOS deployments.
Critical Impact
An enrolled user with local access can unenroll a managed Chromebook and intercept device management traffic, undermining enterprise MDM controls.
Affected Products
- Google ChromeOS 15823.23.0
- Chromebook hardware running the affected ChromeOS build
- Enterprise-enrolled ChromeOS devices managed through Google Admin

Technical Details for CVE-2025-1704
Vulnerability Analysis
The vulnerability targets the ChromeOS ComponentInstaller subsystem. ComponentInstaller retrieves and loads updatable components from the device's stateful partition at runtime. Because the stateful partition is not encrypted at rest in the affected scenario, a user with local access can write or modify component payloads before they are loaded. When ChromeOS subsequently invokes the tampered component, it executes code paths that permit unenrollment of a device that policy would otherwise lock into enterprise management.
The attack scope is limited to users who already have local access to an enrolled device. However, the impact extends beyond that device because the attacker can then intercept and respond to device management requests that flow to Google's management endpoints. This breaks the assumption that enrolled devices cannot escape enterprise policy without administrator action.
Root Cause
The root cause is a trust boundary violation. ComponentInstaller loads components from an unencrypted, user-writable location without sufficient integrity enforcement to prevent locally staged modifications from altering enrollment state. Additional details are tracked in the Chromium Issue Tracker Entry and the Google Issue Tracker Entry.
Attack Vector
Exploitation requires an authenticated local user on an enrolled Chromebook. The attacker stages a modified component in the unencrypted stateful partition, triggers ComponentInstaller to load it, and uses the resulting code path to unenroll the device. Once unenrolled, the attacker can position a local proxy to intercept subsequent device management requests. No user interaction beyond the attacker's own session is required.
No public proof-of-concept exploit is currently listed for this issue, and it is not present in the CISA Known Exploited Vulnerabilities catalog. See the Chromium Issue Tracker Entry for technical specifics.
Detection Methods for CVE-2025-1704
Indicators of Compromise
- Unexpected transitions of a managed Chromebook from an enrolled to an unenrolled state in Google Admin console reports.
- Modifications or unexpected files in the ChromeOS stateful partition component directories.
- Device management heartbeat traffic that stops originating from a known-enrolled device or begins terminating at non-Google endpoints.
Detection Strategies
- Monitor the Google Admin console for enrollment state changes, device deregistration events, and gaps in policy check-in cadence for managed Chromebooks.
- Correlate network telemetry for managed Chromebooks against expected Google device management destinations to identify redirected or intercepted requests.
- Track ChromeOS version reporting and flag devices that remain on 15823.23.0 after a patched release is available.
Monitoring Recommendations
- Alert on any managed Chromebook that ceases policy compliance reporting for longer than the organizational threshold.
- Ingest ChromeOS device audit logs into a centralized data lake for retention and correlation with user access events.
- Review physical access controls and user account assignments for shared Chromebooks that could be tampered with by their enrolled users.
How to Mitigate CVE-2025-1704
Immediate Actions Required
- Update all affected Chromebooks to a ChromeOS build later than 15823.23.0 through the standard auto-update channel.
- Force-restart devices that have deferred updates to ensure the patched ChromeOS image is applied.
- Audit the current enrollment status of every managed Chromebook and re-enroll any device found in an unexpected state.
Patch Information
Google addressed the issue in ChromeOS releases following 15823.23.0. Refer to the Chromium Issue Tracker Entry and the Google Issue Tracker Entry for fix details and the specific milestone containing the corrected ComponentInstaller logic. Apply updates through the ChromeOS auto-update service, or use the Google Admin console to pin devices to a fixed minimum version.
Workarounds
- Restrict which user accounts can sign in to enrolled Chromebooks to reduce the population of users with local access.
- Enforce the shortest practical auto-update deferral policy for managed Chromebooks in the Google Admin console.
- Physically secure shared or kiosk Chromebooks and disable developer mode to limit local tampering opportunities.
# Configuration example
# Verify ChromeOS version on a managed device via chrome://version
# and confirm the reported build is greater than 15823.23.0.
# Administrators can pin a minimum version in Google Admin:
# Devices > Chrome > Settings > Device > Auto-update settings
# Set "Minimum Chrome version" above 15823.23.0
