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 vowifiservice, there is a possible missing permission check.This could lead to local escalation of privilege with no additional execution privileges

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

This is a local privilege escalation vulnerability in the vowifiservice component where a missing permission check allows an attacker to gain elevated privileges without requiring additional execution privileges. The vulnerability requires local access to exploit, indicating that an attacker with low-privilege code execution could potentially bypass authorization controls in the WiFi service.

MitigationImplement proper permission checks in the vowifiservice component at all entry points where privileged operations are performed, ensuring callers have the appropriate Android permissions before executing sensitive operations.

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. Confirm Android version is 11.0
    Run 'adb shell getprop ro.build.version.release' or check Settings > About Phone > Android version
    Affected if The reported version is exactly 11.0 (not 11.0 update versions or other Android releases)
  2. Verify vowifiservice component exists
    Run 'adb shell dumpsys -l | grep vowifiservice' to list the service if registered in the system
    Affected if The vowifiservice component is found in the service registry
  3. Check if vowifiservice is running
    Run 'adb shell dumpsys vowifiservice' to query the service status and available operations
    Affected if The service responds and is actively running on the device
  4. Inspect service permission configuration
    Run 'adb shell dumpsys package vowifiservice' or check the service manifest entry for permission enforcement
    Affected if The service lacks proper permission checks at entry points or accepts calls from unprivileged apps

A device is affected if it runs Android version 11.0 and contains the vowifiservice component with missing permission enforcement.
