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 DeviceId of DeviceId.java, there is a possible desync in persistence due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

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

A missing bounds check in the DeviceId persistence logic in DeviceId.java allows an attacker to cause desynchronization of stored device identifiers. This can be exploited locally to escalate privileges, likely through manipulation of array indices or buffer access beyond allocated boundaries in the persistence layer.

MitigationImplement proper bounds validation before any array or buffer access in the DeviceId persistence code to ensure all indices remain within valid ranges.

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. Identify Android version and build
    Run 'getprop ro.build.version.release' and 'getprop ro.build.version.sdk' to determine the Android version and SDK level
    Affected if The device runs any version of Android (as all versions are affected per the advisory)
  2. Locate DeviceId.java component
    Search for the file DeviceId.java in the Android framework system partition (typically under /system/framework/ or within the com.android.internal.telephony package) using 'find /system -name DeviceId.java 2>/dev/null' or decompile system libraries
    Affected if The DeviceId.java file exists in the Android framework, enabling the vulnerable persistence logic
  3. Verify DeviceId persistence feature is in use
    Check if applications or system services access the DeviceId API (android.provider.DeviceId or similar) by reviewing app manifest permissions and examining logcat for DeviceId-related operations
    Affected if DeviceId persistence is actively used by any app or system service on the device, creating an attack surface
  4. Check for apps with elevated privileges
    List installed privileged applications (system apps in /system/priv-app/) that may interact with device identity storage: 'ls /system/priv-app/' and review which apps hold READ_PHONE_STATE or similar permissions
    Affected if Privileged applications exist that could potentially be targeted for privilege escalation via the vulnerability

A device is affected if it runs any version of Android and contains the DeviceId.java component with its persistence functionality accessible to local attackers.
