Last modified

CVE-2024-36354 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
