Privileged data disclosure via PdaSmm race
Published Mar 10, 2026 · Updated Mar 10, 2026
Information disclosure in Intel UEFI Reference Firmware's PdaSmm module allows local users with high privileges to expose protected data. Intel identifies a time-of-check time-of-use race in PdaSmm but has not disclosed the checked resource or the operations separated by the race window. Exploitation has high attack complexity on an affected Intel Xeon 6 or Atom P6000 reference platform, requires no user interaction, and affects confidentiality only.

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?
