Memory disclosure via buffer over-read
Published Oct 17, 2024 · Updated Aug 19, 2026
Buffer over-read in Microsoft Edge (Chromium-based) before 130.0.2849.46 allows remote attackers to disclose process memory via web content. Microsoft identifies CWE-126 but has not disclosed the affected component or the bounds operation that reads beyond its buffer. Exploitation requires user interaction, and Microsoft's published vector limits the demonstrated consequence to confidentiality loss.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
