About this tag
The attestations vex csaf tag covers discussions about Microsoft's product-scoped inventory attestations for Linux kernel vulnerabilities, particularly in Azure Linux. Threads examine how Microsoft's CSAF (Common Security Advisory Framework) and VEX (Vulnerability Exploitability eXchange) documents, such as those for CVE-2024-39484 and CVE-2024-35870, provide attestations that a product includes a vulnerable open-source library but do not guarantee that no other Microsoft product contains the same code. The content highlights gaps in coverage and the importance of understanding the scope of these attestations for accurate vulnerability management.
