CVE-2025-54518

Quick assessment

Affected
AMD AMD EPYC™ 7002 Series Processors
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

AMD EPYC Processor是美国超威半导体（AMD）公司的一系列多核处理器。 AMD EPYC Processor存在安全漏洞，该漏洞源于在基于Zen 2的产品上，对CPU操作缓存中的共享资源进行不当隔离可能会使攻击者破坏在不同特权级别上执行的指令，从而可能导致特权升级。
