CVE-2025-54518: CWE-1189 Improper Isolation of Shared Resources on System-on-a-Chip (SoC) in AMD AMD EPYC™ 7002 Series Processors
CVE-2025-54518 is a high-severity vulnerability affecting AMD EPYC™ 7002 Series Processors based on the Zen 2 architecture. It involves improper isolation of shared resources within the CPU operation cache, which could allow an attacker with limited privileges to corrupt instructions executed at a higher privilege level. This corruption may lead to privilege escalation. No official patch or remediation guidance has been provided by the vendor at this time. There are no known exploits in the wild. The vulnerability has a CVSS 4.0 base score of 7.3, indicating a significant risk if exploited.
AI Analysis
Technical Summary
This vulnerability (CVE-2025-54518) concerns improper isolation of shared resources in the CPU operation cache of AMD EPYC™ 7002 Series Processors (Zen 2-based). The flaw allows an attacker with low privileges to interfere with instructions running at higher privilege levels by corrupting them through shared cache resources. This could potentially enable privilege escalation attacks. The CVSS 4.0 vector indicates the attack requires local access with high attack complexity and no user interaction, and that it impacts confidentiality, integrity, and availability with high severity. No official remediation or patch is currently documented.
Potential Impact
If exploited, this vulnerability could allow a local attacker with limited privileges to corrupt instructions executed at higher privilege levels, potentially resulting in privilege escalation. This could compromise system integrity and security. However, there are no known exploits in the wild, and no official patch or mitigation has been released by AMD as of the published date.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official remediation or patch is currently available, users should monitor AMD's advisories for updates. Until a fix is provided, restricting local access to trusted users and minimizing exposure to untrusted code execution may reduce risk.
