CVE-2022-48248
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 audio 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 confidenceIn the audio service (likely Android), a missing permission check allows a local attacker to escalate privileges without additional execution privileges. This could let an app bypass normal permission boundaries to access audio-related functionality it shouldn't have access to.

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.
-
Identify Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The version is 10, 11, 12, or 13
-
Check audio service packageRun 'dumpsys package android.audio' via ADB shell to list the audio service component and its permissionsAffected if The audio service component is exposed without proper permission enforcement
-
Verify audio service permissionsRun 'dumpsys package <audio_service_package>' to inspect the manifest-defined permissions for the audio serviceAffected if No signature or privileged permissions are required for core audio operations
-
Test audio service access controlAttempt to call a protected audio API from an untrusted app (e.g., AudioManager methods that should require AUDIO permission) using an adb shell app with minimal privilegesAffected if The untrusted app can execute audio service operations without receiving a SecurityException
If the Android version is 10, 11, 12, or 13 AND the audio service allows access from untrusted apps without proper permission verification, the environment is affected by this CVE.

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 audio service to verify caller identity before granting access to sensitive operations. Apply any available security patches for the audio service component.
