Privileged escalation via debug interface access-control failure
Published Mar 14, 2024 · Updated Feb 13, 2025
Improper access control in 4th Generation Intel Xeon processors allows local privileged users to escalate privileges when SGX or TDX is active. The on-chip debug and test interface fails to enforce required access restrictions, although Intel has not disclosed the specific transaction or register path involved. Exploitation requires privileged local access and an affected processor configured for SGX or TDX, placing protected enclave or trust-domain confidentiality and integrity at risk.

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?
