CVE-2025-54502 AMD CVE debrief

Who should care

Organizations using AMD-based systems should prioritize patching this vulnerability. System administrators and security teams responsible for maintaining systems with AMD processors are advised to review the AMD security bulletin and apply necessary updates. Additionally, Red Hat users can find relevant information and potential patches through their security portals and Bugzilla reports.

Technical summary

The vulnerability is caused by the incorrect use of boot service in the AMD Platform Configuration Blob (APCB) SMM driver. This could allow a privileged attacker with local access (Ring 0) to achieve privilege escalation. The vulnerability's CVSS vector is CVSS:4.0/AV:L/AC:H/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X. CWE-668 and CWE-648 are associated with this vulnerability.

Defensive priority

High priority should be given to patching this vulnerability due to its potential for privilege escalation and arbitrary code execution. System administrators should review the AMD security bulletin (AMD-SB-7054) and apply necessary updates.

Recommended defensive actions

• Review and apply the AMD security bulletin (AMD-SB-7054) updates.
• Check Red Hat security portals and Bugzilla reports for relevant information and potential patches.
• Inventory systems with AMD processors to ensure they are patched.
• Monitor system logs for potential exploitation attempts.
• Implement compensating controls to detect and prevent local privilege escalation attacks.
