CVE-2024-21944: CWE-20 Improper input validation in AMD AMD EPYC™ 7003 Series Processors
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 potentially overwrite guest memory resulting in loss of guest data integrity.
AI Analysis
Technical Summary
This vulnerability arises from improper input validation of DIMM SPD metadata in AMD EPYC 7003 Series Processors. Exploitation requires high privileges such as physical access, ring0 access on a system with a non-compliant DIMM, or control over the BIOS update Root of Trust. Successful exploitation could lead to overwriting guest memory, resulting in compromised guest data integrity. The CVSS 3.1 base score is 5.3, reflecting medium severity with a complexity of high and requiring high privileges. No vendor advisory or patch information is currently available.
Potential Impact
The impact is limited to loss of guest data integrity through potential guest memory overwrite. There is no confidentiality or availability impact indicated. Exploitation requires significant privileges or physical access, limiting the attack surface.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix or mitigation is provided by AMD, ensure that only compliant DIMMs are used and restrict physical and ring0 access to trusted parties. Monitor AMD advisories for updates.
