Local information disclosure via out-of-bounds read
Published Aug 8, 2023 · Updated Aug 10, 2026
Out-of-bounds read in Microsoft Windows WwanSvc allows local users to disclose sensitive memory through a crafted local request. Microsoft identifies the faulty operation but has not published the affected function, malformed field, or precise request-processing path. A low-privileged local account is required; successful exploitation exposes memory contents without changing data or interrupting service.
