CVE-2025-54505: CWE-1420 Exposure of Sensitive Information during Transient Execution in AMD AMD EPYC™ 7001 Series Processors
CVE-2025-54505 is a transient execution vulnerability affecting AMD EPYC™ 7001 Series processors. It allows a local user-privileged attacker to potentially leak sensitive data through the floating point divisor unit. The vulnerability could result in a loss of confidentiality but requires local access and privileges to exploit. The CVSS 4. 0 score is low (2. 0), reflecting limited impact and exploitability. No official patch or remediation guidance is currently available from AMD. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability involves transient execution within AMD EPYC™ 7001 Series CPUs that may expose sensitive information via the floating point divisor unit. A local attacker with user-level privileges could exploit this flaw to leak data, leading to confidentiality breaches. The CVSS 4.0 vector indicates low attack complexity and privileges required, but the overall impact is limited. No vendor-provided patch or mitigation details are currently published.
Potential Impact
The impact is limited to potential confidentiality loss of sensitive data accessible via transient execution side channels in the floating point divisor unit. Exploitation requires local user privileges, and there is no indication of privilege escalation or integrity/availability impact. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the AMD vendor advisory for current remediation guidance. Until an official fix is released, restrict local user access to trusted parties and monitor for updates from AMD. No specific mitigations are currently documented.
