Physical information disclosure via out-of-bounds read
Published Dec 10, 2024 · Updated Jun 9, 2026
Out-of-bounds read in Microsoft Windows WwanSvc allows physically proximate attackers with low privileges to disclose memory contents. Microsoft identifies the Wireless Wide Area Network Service as the affected component but does not publish the specific read operation or input that crosses its buffer boundary. Physical access and existing low privileges are required; the documented impact is confidentiality loss without integrity or availability effects.
