Physical access to protected data
Published Jun 9, 2026 · Updated Jun 9, 2026
Protection mechanism failure in Windows BitLocker allows physically proximate attackers to read protected data without credentials. Microsoft has not disclosed the flawed BitLocker component or the operation that fails to enforce the protection mechanism. Physical access to an affected Windows device is required, and the documented impact is disclosure of protected data without reported integrity or availability effects.
