Physical privilege escalation via out-of-bounds driver read
Published Dec 10, 2024 · Updated Jun 9, 2026
An out-of-bounds read in the Windows Mobile Broadband Driver allows physically proximate attackers to elevate privileges on affected Windows systems. Microsoft identifies the flaw as an out-of-bounds read but has not published the driver routine, input structure, or boundary check that fails. Successful exploitation requires physical access, needs no prior privileges or user interaction, and compromises confidentiality, integrity, and availability.
