Local information disclosure via out-of-bounds read
Published Sep 8, 2026 · Updated Sep 9, 2026
Out-of-bounds read in Windows Wireless Wide Area Network Service allows local users to disclose information from affected Windows systems. Microsoft identifies the component and the out-of-bounds read, but has not disclosed the specific routine, buffer, or input that triggers the invalid read. A low-privileged local user must reach the service; the consequence is limited to reading memory beyond the intended buffer, with no integrity or availability impact reported.
