CVE-2024-36354
Intel DIMM SMM Isolation Bypass Vulnerability
Overview
Description
Improper input validation for DIMM serial presence detect (SPD) metadata could allow an attacker with physical access, ring0 access on a system with a non-compliant DIMM, or control over the Root of Trust for BIOS update, to bypass SMM isolation potentially resulting in arbitrary code execution at the SMM level.

Solution
Update system firmware to validate DIMM SPD metadata and prevent SMM bypass.
- Update system firmware to the latest version.
- Validate DIMM SPD metadata during system initialization.
- Ensure SMM isolation is properly enforced.
- Restrict physical and root access to the system.
