CVE-2024-36345: CWE-1274 Improper Access Control for Volatile Memory Containing Boot Code in AMD AMD EPYC™ 4004
Improper input validation in the AMD OverDrive (AOD) System Management Mode (SMM) module could allow a privileged attacker to perform an out-of-bounds read, potentially resulting in loss of confidentiality.
AI Analysis
Technical Summary
This vulnerability (CVE-2024-36345) affects the AMD OverDrive (AOD) System Management Mode (SMM) module in AMD EPYC™ 4004 processors. Due to improper input validation, a privileged attacker can trigger an out-of-bounds read in volatile memory that contains boot code. The issue is classified under CWE-1274 (Improper Access Control for Volatile Memory Containing Boot Code). The CVSS 4.0 base score is 4.6 (medium severity), reflecting local attack vector, low confidentiality impact, and no required user interaction. No patch or official remediation guidance has been published by AMD as of the provided data.
Potential Impact
The vulnerability allows a local attacker with high privileges to read memory beyond intended boundaries, potentially exposing confidential boot code data. This could compromise confidentiality but does not indicate integrity or availability impacts. There are no known exploits in the wild. The attack requires privileged local access, limiting the attack surface.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or remediation level is provided by AMD, organizations should monitor AMD advisories for updates. Until a patch is available, restrict privileged access to trusted users only to reduce risk.
