CVE-2025-54505: CWE-1420 Exposure of Sensitive Information during Transient Execution in AMD AMD EPYC™ 7001 Series Processors
A transient execution vulnerability within AMD CPUs may allow a local user-privileged attacker to leak data via the floating point divisor unit, potentially resulting in loss of confidentiality.
AI Analysis
Technical Summary
This vulnerability involves transient execution in AMD EPYC™ 7001 Series processors, where a local attacker with user privileges may exploit the floating point divisor unit to leak sensitive information. The issue is classified under CWE-1420 (Exposure of Sensitive Information during Transient Execution). The CVSS 4.0 vector indicates low attack complexity and low impact on confidentiality, with no impact on integrity or availability. No official remediation or patch has been announced by AMD as of the publication date.
Potential Impact
The impact is limited to potential confidentiality loss of sensitive data accessible to a local user-privileged attacker. There is no indication of integrity or availability impact. The low CVSS score reflects a low severity risk. 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. Since no official fix or mitigation level is provided by AMD, users should monitor AMD advisories for updates. No specific mitigation actions are currently recommended by the vendor.
