CVE-2024-21981

Quick assessment

Affected
AMD AMD EPYC™ 7001 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 Secure Processor（ASP）是美国超威半导体（AMD）公司的一款独立的 ARM Coretex-A5 芯片。 AMD Secure Processor(ASP)、AMD Secure Encrypted Virtualization(SEV)和AMD Secure Encrypted Virtualization-Secure Nested Paging(SEV-SNP)存在安全漏洞，该漏洞源于密钥使用控制不当，可能允许具有本地访问权限且已获得ASP中任意代码执行权限的攻击者提取AS
