Information disclosure via out-of-bounds memory read
Published Nov 11, 2025 · Updated Feb 13, 2026
Out-of-bounds read in Microsoft Excel allows attackers to disclose information when a user opens affected spreadsheet content locally. Microsoft has not disclosed the parser or code path that reads beyond its intended memory boundary while processing the content. Exploitation requires user interaction and local execution context; it can expose memory contents and interrupt the affected application, with no integrity impact reported.
