Local privilege escalation via TDX.sys buffer over-read
Published Nov 11, 2025 · Updated Feb 26, 2026
Buffer over-read in Microsoft Windows TDX.sys allows local users with basic privileges to elevate privileges on affected Windows systems. Microsoft identifies the faulty operation as an over-read in the TDI translation driver but has not disclosed the input, code path, or missing boundary check that permits it. Exploitation requires local low-privileged access and no user interaction; success grants privileges beyond the attacker's existing account.
