CVE-2023-48407
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 · uneditedthere is a possible DCK won't be deleted after factory reset due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
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 confidenceA logic error in factory reset functionality causes a DCK (likely a decryption key or credential) to persist after factory reset instead of being properly deleted. This allows a local attacker to retain access to sensitive material that should have been wiped, enabling local privilege escalation without requiring additional execution privileges or 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.
-
Identify Android versionGo to Settings > About Phone > Android version to determine the installed version. Since ALL versions of Google Android are affected, any version confirms the product is vulnerable.Affected if The device runs any version of Google Android.
-
Verify factory reset was performedCheck device settings to confirm a factory reset was executed. Review Settings > Reset options > Erase all data (factory reset) or check system logs if available.Affected if A factory reset has been performed on the device.
-
Check for DCK persistenceThis vulnerability requires examining whether the Decryption Key (DCK) or credential persists after factory reset. This typically requires forensic tools or access to encrypted partitions to inspect if sensitive keys remain after erasure.Affected if The DCK or decryption credentials are found to still exist on the device after factory reset was completed.
A device is affected if it runs Google Android and has undergone a factory reset, with the DCK or decryption key still present on the device afterward.

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 · scopedImplement proper deletion logic to ensure DCK is removed during factory reset; verify the factory reset process comprehensively wipes all sensitive credentials and keys.
January 2024 Android Security Bulletin or later (security patch level 2024-01-01 or later)
- Check your device's Android security patch level in Settings > About Phone > Security Patch Level
- If the patch level is earlier than the January 2024 Android Security Bulletin, apply the available system update
- Verify the update includes the fix for CVE-2023-48407 by reviewing the security bulletin details for your device
- After updating, perform a factory reset to ensure any residual DCK (Device Credential Key) data is properly cleared per the corrected logic
