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 linkturbonative service, there is a possible command injection due to improper input validation. This could lead to local escalation of privilege with System 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

A command injection vulnerability exists in the linkturbonative service due to improper input validation. This allows a local attacker with System execution privileges to inject and execute arbitrary commands, achieving local privilege escalation.

MitigationImplement strict input validation and sanitization for all user-controlled inputs that reach system calls or command execution functions within the linkturbonative service.

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. Verify Android version
    Run 'getprop ro.build.version.release' or check Settings > About Phone > Android version to determine if the device runs Android 13.0 or 14.0
    Affected if Android version is exactly 13.0 or 14.0
  2. Identify linkturbonative service
    Run 'pm list packages | grep linkturbo' or check for the presence of the linkturbonative service using 'ps -A | grep linkturbo'
    Affected if The linkturbonative package or process is present on the device
  3. Check service execution context
    Run 'dumpsys package <package_name>' to inspect the linkturbonative service permissions and verify if it runs with System or higher privileges
    Affected if The service runs with System user privileges or higher (UID 1000 or below)
  4. Inspect service configuration
    Check /data/system/packages.xml or use 'appops get <package_name>' to review the operational permissions granted to the linkturbonative service
    Affected if The service has broad system execution capabilities or shell command access enabled

A device is affected if it runs Android 13.0 or 14.0 AND has the linkturbonative service installed running with System-level execution privileges.
