Privileged local firmware-context data exposure
Published Mar 10, 2026 · Updated Mar 10, 2026
Information disclosure in Intel UEFI Reference Firmware allows privileged local users to expose data through the PdaSmm module. Intel identifies exposure of a resource to the wrong control sphere, but does not disclose the resource, the PdaSmm operation that exposes it, or the triggering input. Exploitation requires privileged local system-software access and high attack complexity; the reported consequence is loss of firmware-context confidentiality without integrity or availability impact.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
