CVE-2023-42695
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 · uneditedIn 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 confidenceThis 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify Android version is 10.0Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if Android version equals 10.0 exactly (not 10.0 with later security patches)
-
Confirm wifi service is runningRun 'adb shell dumpsys wifi' to check if the wifi service is active and accessibleAffected if WiFi service is enabled and running on the device
-
Check for unexpected wifi-related processesRun 'adb shell ps -A | grep wifi' to list wifi-related processes and look for unknown or suspicious processesAffected if Unexpected processes with wifi service permissions are present
-
Review wifi service logs for permission bypass attemptsRun 'adb shell logcat -d | grep -i wifi' and search for permission-related denials or unusual service callsAffected if Logs show permission check failures or unexpected wifi service invocations from apps
-
Check for unauthorized privilege escalation indicatorsRun 'adb shell dmesg' and look for any privilege escalation signatures or unexpected root access attemptsAffected 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.

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.
From vendor dataApply 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.
