CVE-2024-43458Network attack vector

Authenticated information disclosure via uninitialized resource

Published Sep 10, 2024 · Updated Aug 10, 2026

Information disclosure in Windows 10 Version 1607 and Windows Server 2016 before 10.0.14393.7336 allows remote authenticated users to read data. Microsoft identifies the underlying weakness as use of an uninitialized resource but has not disclosed the networking component, resource, or operation that exposes its contents. Exploitation requires low privileges and network access; the demonstrated consequence is limited to confidentiality, with no integrity or availability impact.
