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 Connectivity Service, 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 Android's Connectivity Service caused by a missing permission check. An attacker with local access can exploit this to gain elevated privileges without requiring additional execution privileges. The vulnerability has a CVSS base score of 7.8, indicating high severity but with a local attack vector.

MitigationApply the latest Android security patch level from the device manufacturer or OS provider, as this is a system service vulnerability that requires a platform-level fix.

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 version number
    Go to Settings > About Phone > Android version, or execute 'getprop ro.build.version.release' via ADB shell
    Affected if Version is exactly 10.0 (the only affected version)
  2. Confirm Android build ID
    Run 'getprop ro.build.id' via ADB shell to get the full build identifier
    Affected if Build is associated with Android 10.0 release
  3. Verify Connectivity Service is running
    Run 'dumpsys connectivity' or 'ps -A | grep connectivity' via ADB shell to confirm the service is active
    Affected if Connectivity Service is present and running on an Android 10.0 device
  4. Assess local access exposure
    Check Developer Options > USB debugging status, or determine if the device permits local shell access through other means
    Affected if ADB debugging is enabled or the device permits local command execution by untrusted users

The environment is affected only if it runs Android version exactly 10.0 and an attacker can execute local commands on the device.
