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.
-
Confirm Android version is 13.0Go to Settings > About Phone > Android version. Alternatively, run 'getprop ro.build.version.release' via ADB shell.Affected if Version displays anything other than 13.0, as this CVE specifically affects Android 13.0 only
-
Check Security Patch LevelGo to Settings > About Phone > Security patch level. Alternatively, run 'getprop ro.build.version.security_patch' via ADB shell.Affected if The patch level is earlier than the Android security bulletin containing CVE-2023-21193 fix (typically the May 2023 or later security update)
-
Verify VideoFrame processing is in useThis vulnerability exists in the VideoFrame component. Check if any video capture, video playback, or video conferencing apps are actively processing video on the device.Affected if The device actively processes video frames and the Security Patch Level is unpatched for this CVE
The device is affected if it runs Android 13.0 and has a Security Patch Level predating the CVE-2023-21193 fix, with VideoFrame processing actively occurring.

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.
dbcve · scopedApply the Android security patch for CVE-2023-21193 (part of Android-13 security update bundle). Organizations should ensure Android devices receive timely system updates from device vendors.
Android 13.0 with later security patch level (any 2023 or later Android security update)
- 1. Go to Settings on the Android device
- 2. Navigate to System > Security & privacy > Security update
- 3. Check for and install any available Android security updates
- 4. Verify the device is running a security patch level that includes the fix for CVE-2023-21193 (any Android 13 security update released after the vulnerability was disclosed)
