CVE-2019-2008
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 createEffect of AudioFlinger.cpp, there is a possible memory corruption due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.Product: AndroidVersions: Android-8.0 Android-8.1 Android-9Android ID: A-122309228
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 · high confidenceA race condition in the createEffect function of Android's AudioFlinger.cpp allows local attackers to corrupt memory, potentially achieving privilege escalation without additional execution privileges. The vulnerability stems from insufficient synchronization when creating audio effects, which can be triggered via user interaction.

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 Android OS versionRun 'getprop ro.build.version.release' in a shell or go to Settings > About Phone > Android versionAffected if The version is 8.0, 8.1, or 9.0
-
Verify AudioFlinger service is activeRun 'ps -A | grep audioflinger' or 'dumpsys audioflinger' via ADB shellAffected if The AudioFlinger service process is running on the device
-
Confirm audio effect creation capabilityCheck if applications can access audio effect APIs via 'dumpsys audio' or review audio policy configuration at /system/etc/audio_policy.xmlAffected if Audio effect creation is permitted and the AudioFlinger module is loaded
-
Inspect AudioFlinger process for race condition indicatorsRun 'logcat -v time | grep -i audioflinger' to examine system logs for crash or corruption messages related to effect creationAffected if Logs show unexpected behavior, crashes, or memory corruption events involving AudioFlinger during audio effect operations
A device is affected if it runs Android 8.0, 8.1, or 9.0 with an active AudioFlinger service where audio effects can be created, and exhibits abnormal behavior during effect operations.
Generated from the published advisory. Verify against your own configuration.
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-2019-2008 which adds proper synchronization primitives to the createEffect function in AudioFlinger to prevent the race condition. Until patch availability, monitor device usage for unusual audio service behavior.
