Physical security bypass via undisclosed workflow flaw
Published Oct 14, 2025 · Updated Oct 14, 2025
Security-feature bypass in Microsoft Windows BitLocker allows physically proximate attackers to read or alter protected drive data. Microsoft identifies improper enforcement of a behavioral workflow but has not published the affected BitLocker locus or the operation that mishandles the workflow. Physical access to an affected Windows device is required; successful exploitation defeats BitLocker confidentiality and integrity without interrupting availability.
