About this tag
CVE-2025-38461 is a kernel time-of-check/time-of-use (TOCTOU) race condition vulnerability in the vsock transport layer. Discussions on WindowsForum clarify that Microsoft's advisory stating Azure Linux includes the affected open-source library is a product-scoped inventory attestation, not proof that other Microsoft products are unaffected. The vulnerability involves a race where code checks a condition on an object and then uses it later, potentially leading to security issues. Users seeking details on CVE-2025-38461 will find analysis of its scope and Microsoft's response, emphasizing the need to verify which products are truly impacted beyond Azure Linux.
Microsoft’s short MSRC advisory that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate — but it is a product‑scoped inventory attestation, not proof that no other Microsoft product can or does include the same vulnerable code.
