CVE-2023-48267

Privilege escalation via improper buffer restrictions

Published Feb 12, 2025 · Updated Feb 26, 2026

Improper buffer restrictions in Intel System Security Report and System Resources Defense firmware allow local users to escalate privileges. Intel identifies only a firmware memory-buffer bounds failure and has not disclosed the affected component, malformed input, or incorrect operation. Exploitation requires high privileges and local access, and successful abuse compromises confidentiality and integrity without directly interrupting service.
