Protection mechanism failure in Windows BitLocker allows an unauthorized attacker to bypass a security feature with a physical attack.

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 confidence

CVE-2025-48003 is a protection mechanism failure vulnerability in Windows BitLocker that allows an unauthorized attacker to bypass a security feature via a physical attack. The vulnerability enables circumvention of BitLocker's encryption protection when an attacker has physical access to the affected system.

MitigationOrganizations should implement additional physical security controls and monitor for unauthorized physical access attempts. Review BitLocker configuration and ensure TPM protection is properly enabled and configured.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Windows version and build number
    Open Command Prompt or PowerShell and run 'winver' or 'systeminfo | findstr /B /C:"OS Version"' to get the exact build number. Compare this to the affected version ranges listed in the CVE.
    Affected if The installed Windows version build number is lower than the fixed version for your specific Windows release (e.g., Windows 10 1809 build < 17763.7558, Windows 11 22h2 build < 22621.5624, etc.)
  2. Verify BitLocker is enabled
    Open an elevated Command Prompt and run 'manage-bde -status' or use PowerShell with 'Get-BitLockerVolume' to see if BitLocker encryption is active on any drives.
    Affected if BitLocker is not enabled on the system drives, as the vulnerability only affects systems where BitLocker protection is in use.
  3. Check BitLocker protection status
    Run 'manage-bde -status C:' or use PowerShell 'Get-BitLockerVolume -MountPoint C:' to see whether protection is 'On', 'Paused', or 'Off'.
    Affected if BitLocker protection status shows 'Paused' or 'Off', indicating the volume is not actively protected.
  4. Confirm TPM protector status
    Run 'manage-bde -status C:' and look for the 'Key Protectors' section, or use PowerShell 'Get-BitLockerVolume | Select-Object -ExpandProperty ProtectionStatus' to verify TPM is configured as a key protector.
    Affected if TPM-based protection is not configured as a key protector, as the bypass relates to physical attack scenarios against TPM-protected systems.

A system is affected if it runs a Windows version with a build number lower than the fixed version AND has BitLocker enabled with TPM protection, as the vulnerability enables physical attack bypass of BitLocker encryption.

  1. Identify the current Windows version by running 'winver' or 'systeminfo' in Command Prompt
  2. Determine if your current version is below the fixed threshold for your Windows release
  3. Apply the appropriate Windows security update for your version: For Windows 10 1809/Windows Server 2019, upgrade to 10.0.17763.7558 or later; For Windows 10 21h2, upgrade to 10.0.19044.6093 or later; For Windows 10 22h2, upgrade to 10.0.19045.6093 or later; For Windows 11 22h2, upgrade to 10.0.22621.5624 or later; For Windows 11 23h2, upgrade to 10.0.22631.5624 or later; For Windows 11 24h2, upgra
  4. Install the update via Windows Update, WSUS, or by downloading the update from the Microsoft Update Catalog
  5. Restart the system as required by the update
  6. Verify the installed version matches or exceeds the fixed version for your Windows release
Caveat Standard Windows update risks apply - ensure backups exist and test in non-production environments before broad deployment
