About this tag
CSAF VEX attestations are machine-readable security documents published by Microsoft to formally declare which products are affected by specific CVEs. On WindowsForum, discussions center on Microsoft's product-level attestations for Azure Linux, where the company confirms that a vulnerable open-source component is present in that distribution. These attestations are authoritative for Azure Linux but do not guarantee that no other Microsoft artifact contains the same vulnerability. Users learn to interpret the scope of CSAF/VEX statements, understand that unverified products remain unknown, and apply remediation only to attested products. The tag covers how to read, trust, and act on these attestations in enterprise environments.
