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.
-
Verify Android version is affectedCheck the device Android version in Settings > About Phone > Android version. The affected versions are Android 10.0, 11.0, and 12.0.Affected if The device is running Android 10.0, 11.0, or 12.0 and has not received the April 2022 security patch.
-
Identify Quram Agif library presenceSearch for the file libquramgif.so or libagif library files in the system partition, typically under /system/lib or /vendor/lib directories. This library handles animated GIF processing.Affected if The Quram Agif library (libquramgif.so or similar) is present on the device.
-
Check library version or patch dateInspect the library file properties or check system build information for the security patch level. The vulnerability was patched in Samsung's April 2022 SMR (Security Maintenance Release).Affected if The security patch level is earlier than April 2022, indicating the library has not been updated.
-
Confirm GIF processing capabilityDetermine if any installed applications use the Quram Agif library for processing animated GIF files. This library is commonly used by messaging, social media, or image viewer applications.Affected if Applications on the device process animated GIF files using the vulnerable Quram Agif library.
A device is affected if it runs Android 10.0, 11.0, or 12.0 with the Quram Agif library present and a security patch level prior to the April 2022 update.

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 Samsung's SMR April-2022 Release 1 or later, which includes the patched Quram Agif library. Until the update is available, avoid processing untrusted GIF files from unknown sources.
SMR Apr-2022 Release 1 (Security Patch Level April 2022)
- Check current Samsung Android security patch level in Settings > About phone > Software information > Security patch level
- Navigate to Settings > Software update > Download and install
- Ensure the device updates to SMR Apr-2022 Release 1 or later which contains the fix for the Quram Agif library vulnerability
