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 wifi service, there is a possible missing permission check. This could lead to local escalation of privilege 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

This is a local privilege escalation vulnerability in the wifi service where a permission check is missing, allowing an attacker to gain elevated privileges without requiring any additional execution privileges. The vulnerability exists in the wifi service component and requires local access to exploit.

MitigationApply the vendor patch for CVE-2023-42695 which adds the missing permission check in the wifi service. Until a patch is available, restrict local access to untrusted applications and monitor for unusual wifi service behavior.

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 is 10.0
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB
    Affected if Android version equals 10.0 exactly (not 10.0 with later security patches)
  2. Confirm wifi service is running
    Run 'adb shell dumpsys wifi' to check if the wifi service is active and accessible
    Affected if WiFi service is enabled and running on the device
  3. Check for unexpected wifi-related processes
    Run 'adb shell ps -A | grep wifi' to list wifi-related processes and look for unknown or suspicious processes
    Affected if Unexpected processes with wifi service permissions are present
  4. Review wifi service logs for permission bypass attempts
    Run 'adb shell logcat -d | grep -i wifi' and search for permission-related denials or unusual service calls
    Affected if Logs show permission check failures or unexpected wifi service invocations from apps
  5. Check for unauthorized privilege escalation indicators
    Run 'adb shell dmesg' and look for any privilege escalation signatures or unexpected root access attempts
    Affected if Device shows signs of unauthorized privilege escalation with wifi service as the source

A device is affected if it runs Android version 10.0 and has the wifi service enabled, as the missing permission check in this specific version allows local privilege escalation through the wifi service component.
