Local information disclosure via out-of-bounds read
Published Sep 8, 2026 · Updated Sep 9, 2026
Out-of-bounds read in Microsoft Office Word allows local users to disclose information by opening a crafted document. Microsoft identifies Word as the affected component but has not disclosed the parser, file structure, or boundary-check failure that permits the read. Exploitation requires low-privileged local access and user interaction, and the reported consequence is information disclosure without data modification or service interruption.
