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 Network Adapter Service, there is a possible missing permission check. This could lead to local denial of service 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

A missing permission check in the Network Adapter Service allows local attackers to cause a denial of service without requiring elevated privileges. The vulnerability stems from inadequate access controls on certain service operations that should verify user authorization before execution.

MitigationImplement proper permission and authorization checks in the Network Adapter Service to validate user credentials before performing sensitive operations. Restrict service function access based on established privilege boundaries.

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 OS version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if Version is exactly 13.0 or 14.0
  2. Identify Network Adapter Service status
    Run 'dumpsys' command via ADB shell: 'dumpsys -l | grep -i network' or 'dumpsys connectivity' to list network-related services
    Affected if Network Adapter Service is registered and running on the device
  3. Verify service permission configuration
    Run 'dumpsys package <service_name>' if the specific Network Adapter Service name is identifiable, or check SELinux policies via 'getprop' for service context
    Affected if Service allows access from unprivileged contexts without proper permission validation

User is affected if Android version is exactly 13.0 or 14.0 and the Network Adapter Service is exposed without proper permission enforcement to local unprivileged callers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement proper permission and authorization checks in the Network Adapter Service to validate user credentials before performing sensitive operations. Restrict service function access based on established privilege boundaries.
