Code execution through undisclosed ReFS flaw
Published Jan 11, 2022 · Updated Jan 2, 2025
Remote code execution in Microsoft Windows ReFS allows physically proximate attackers to execute code through an undisclosed flaw. Microsoft has not disclosed the faulty ReFS parser locus or the malformed structure that triggers unsafe processing. Physical access to attach attacker-controlled ReFS media is required; successful exploitation compromises the affected Windows system.
