Unauthenticated data disclosure via integer overflow
Published Oct 17, 2024 · Updated Aug 19, 2026
Integer overflow in Microsoft Edge (Chromium-based) before 130.0.2849.46 allows remote attackers to read confidential data. Microsoft identifies an integer overflow or wraparound but has not published the affected component, arithmetic operation, or triggering input. No privileges or user interaction are required; Microsoft's RCE title is broader than its published confidentiality-only vector.
