Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In opm service, there is a missing permission check. This could lead to local information disclosure with no additional execution privileges needed.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The OPM service lacks proper permission verification before allowing access to sensitive data, enabling any local user to read information they should not have access to without requiring elevated privileges.

MitigationImplement comprehensive authorization checks in the OPM service to verify user permissions before granting access to sensitive information and data resources.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Android version
    Retrieve the device Android version via Settings > About Phone > Android version, or use 'getprop ro.build.version.release' command in ADB shell
    Affected if The installed version is 10.0, 11.0, 12.0, or 13.0, matching the affected version ranges
  2. Verify OPM service presence
    Check if the OPM (Output Protection Manager) service is running on the device via 'dumpsys' or process list in ADB shell
    Affected if The OPM service is active and accessible on the device
  3. Test OPM service authorization
    Attempt to access sensitive data through OPM service interfaces without elevated privileges using standard Android APIs or service calls
    Affected if The OPM service returns sensitive data or allows access to protected resources without requiring elevated permissions or proper authorization checks
  4. Inspect OPM service permissions
    Review the OPM service manifest and permission declarations using 'dumpsys package <service_name>' or review the APK manifest
    Affected if The OPM service lacks proper permission verification flags or authorization enforcement in its configuration

If the device runs Android 10.0 through 13.0 and the OPM service is present without proper permission enforcement, unauthorized local users may be able to access sensitive data they should not see.
