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 versionCheck the device's Android version in Settings > About Phone > Android Version. Confirm if it matches 12.0, 13.0, or 14.0.Affected if The device runs Android 12.0, 13.0, or 14.0 exactly.
-
Check Samsung security patch levelLocate the Security Patch Level in Settings > About Phone > Software Information > Security Patch Level. Compare the date to September 2024.Affected if The security patch level is dated before September 2024, indicating the SMR Sep-2024 Release 1 update has not been applied.
-
Confirm Knox/DualDAR feature statusAccess the device's Knox or DualDAR settings (typically under Settings > Security and Privacy > Knox or Settings > Biometrics and Security). Determine whether the dual-encryption or dual-DAR feature is currently enabled or configured.Affected if The DualDAR or dual-encryption security feature is active on the device, making it vulnerable to disruption.
A device is affected if it runs Android 12.0, 13.0, or 14.0, has a pre-September-2024 security patch level, and has the DualDAR/Knox dual-encryption feature enabled.
