CVE-2025-54502
Description
A flaw was found in the AMD Platform Configuration Blob (APCB) SMM driver. A privileged attacker with local access (Ring 0) can exploit an incorrect use of a boot service. This vulnerability may allow the attacker to achieve privilege escalation, potentially leading to arbitrary code execution.
Statement
This is an Important flaw in the AMD Platform Configuration Blob (APCB) SMM driver affecting Red Hat Enterprise Linux on AMD systems. A privileged local attacker (Ring 0) could exploit an incorrect boot service use to achieve privilege escalation, potentially leading to arbitrary code execution. Exploitation requires an attacker to already have high privileges on the system. The fix for this vulnerability is provided by AMD.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
