CVE-2022-47473
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 telephony service, there is a missing permission check. This could lead to local information disclosure 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 missing permission check vulnerability in the Android telephony service that allows any local application to access sensitive telephony information without proper authorization. The flaw enables information disclosure of potentially sensitive subscriber or call-related data to any app installed on the device, since no permission validation occurs before allowing access to the telephony service functionality.

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.
-
Check the Android OS versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The version is 10.0 or 11.0
-
Verify the telephony service is presentCheck if /system/bin/app_process or system_server contains telephony-related services. Use 'dumpsys -l' via ADB shell to list running services and look for 'TelephonyRegistry' or similar telephony servicesAffected if Telephony service is running on an affected Android version (10.0 or 11.0)
-
Confirm no third-party app can access telephony data without permissionsAttempt to observe whether any app without READ_PHONE_STATE or READ_CALL_LOG permissions can retrieve subscriber ID (IMSI), phone number, or call history via the telephony service. This requires code review or dynamic analysis of the telephony service behaviorAffected if Apps without telephony permissions can access sensitive subscriber or call data, confirming the missing permission check
A device is affected if it runs Android 10.0 or 11.0 and the telephony service permits unauthenticated access to sensitive subscriber or call-related information.

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 dataImplement proper permission checks in the telephony service code to verify the calling application holds the required permissions before granting access to sensitive telephony data. Apply the principle of least privilege and validate caller identity using Android's permission framework.
