CVE-2025-27572

Privileged data disclosure via transient execution

Published Feb 10, 2026 · Updated Feb 10, 2026

Transient-execution exposure in Intel TDX Module 1.5.20 and earlier and 2.0.12 and earlier allows local users to read protected data. The Ring 0 hypervisor context transiently exposes sensitive data, but Intel has not disclosed the triggering instruction sequence or data source. Exploitation requires hypervisor-level privileges and high complexity, needs no user interaction, and has no reported integrity or availability impact.
