CVE-2022-33196

Privilege escalation via incorrect memory-controller permissions

Published Feb 16, 2023 · Updated Jan 27, 2025

Incorrect default permissions in Intel Xeon memory-controller settings with SGX allow local privileged users to escalate privileges. Intel has not disclosed which memory-controller permission is initialized incorrectly or how that setting crosses the SGX security boundary. Exploitation requires high local privileges, an affected processor, SGX enabled, and unspecified high-complexity conditions; confidentiality and integrity can be compromised without availability impact.
