Privilege escalation via faulty DDRIO security check
Published Aug 12, 2025 · Updated Feb 26, 2026
Improper security checking in Intel Xeon 6 DDRIO configuration allows local privileged users to escalate privileges in SGX or TDX. The DDRIO configuration implements a standards-mandated security check incorrectly, but Intel has not identified the specific check or faulty operation. Exploitation requires high local privileges and high complexity on an affected Birch Stream server using SGX or TDX, with confidentiality and integrity consequences across the security boundary.
