About this tag
CSAF VEX attestations are machine-readable security advisories published by Microsoft to formally declare which products are affected by specific vulnerabilities. On WindowsForum, discussions center on Azure Linux (formerly CBL-Mariner) and how Microsoft's product-level attestations confirm that Azure Linux includes vulnerable open-source components for CVEs such as CVE-1999-0817, CVE-2025-54090, and others. These attestations are authoritative for Azure Linux but do not guarantee that other Microsoft artifacts are unaffected; operators must perform their own verification. The tag covers the scope, limitations, and practical use of CSAF VEX attestations in enterprise vulnerability management.
