Information disclosure via buffer over-read
Published Sep 8, 2026 · Updated Sep 10, 2026
Buffer over-read in Microsoft Office allows remote attackers to disclose information over a network after user interaction. Microsoft identifies a buffer over-read but does not disclose the affected Office component, input format, or out-of-bounds read operation. Exploitation requires a user to interact with attacker-supplied content, and the reported consequence is limited to information disclosure.
