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 arises from improper input validation in the AMD OverDrive (AOD) System Management Mode (SMM) module on AMD EPYC™ 4004 processors. A privileged attacker could exploit this flaw to perform an out-of-bounds read on volatile memory that contains boot code, potentially exposing confidential information. The CVSS 4.0 base score is 4.6, reflecting a medium severity with local attack vector, low complexity, and no user interaction required. No official remediation or patch has been documented at this time.
Potential Impact
An attacker with privileged access could read memory beyond intended boundaries in the SMM module, potentially disclosing sensitive boot code information. This impacts confidentiality but does not indicate integrity or availability effects. No known exploitation in the wild has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit privileged access to trusted users and monitor for unusual activity related to system management mode operations.
