About this tag
VEX CSAF attestations are machine-readable security statements that vendors like Microsoft use to publicly confirm whether a specific product includes a vulnerable open-source component. On WindowsForum, discussions focus on Microsoft's Azure Linux attestations for CVEs such as CVE-2024-42070, CVE-2024-39483, CVE-2024-43204, CVE-2025-38108, CVE-2024-25178, CVE-2025-47268, and CVE-2023-45288. A recurring theme is that a product-scoped VEX/CSAF attestation identifies Azure Linux as a confirmed carrier of the vulnerable code, but it does not guarantee that other Microsoft artifacts are free of the same component. Defenders must treat the attested product as known affected while independently inventorying other Microsoft-supplied systems. These attestations are valuable for prioritization but require careful interpretation in enterprise security workflows.

  1. CVE-2024-42070 nf_tables: Azure Linux Attestation and Microsoft Kernel Risk

    The short answer is: No — Azure Linux is not necessarily the only Microsoft product that could include the vulnerable nf_tables code, but it is the only Microsoft product Microsoft has publicly attested so far as carrying that upstream component. Microsoft’s advisory is a product-level inventory...

  4. Azure Linux CVE-2025-38099: Audit and Patch the Bluetooth Kernel Bug

    Microsoft’s short public statement — that “Azure Linux includes this open‑source library and is therefore potentially affected” — is accurate, actionable, and deliberately scoped: it confirms Microsoft’s inventory work for the Azure Linux product family, not a universal guarantee that no other...

  7. CVE-2025-37792 Explained: Azure Linux and the Realtek btrtl Bluetooth Driver

    Microsoft’s brief MSRC entry for CVE-2025-37792 — “Bluetooth: btrtl: Prevent potential NULL dereference” — is accurate for the product it names: Azure Linux has been identified as a carrier of the upstream Bluetooth code that required a fix. That attestation, however, is a product‑scoped...
