Microsoft Edge Security Fixes Released Before Major Update

Microsoft Edge 138 Update Enhances Security with Critical Patch

Microsoft has rolled out an update for Edge version 138, specifically version 138.0.3351.121. This release focuses primarily on addressing a significant security flaw rather than introducing new features. Users are encouraged to download this update available in the Stable Channel.

Details of the Security Fix

The recently released update tackles a memory-related vulnerability linked to the Media Stream component of Chromium, which handles audio and video streaming. This particular flaw allows for a situation known as “use after free, ”where the browser continues to access memory that has been released. This can potentially lead to memory corruption, putting users at risk of executing malicious code or experiencing browser crashes.

What’s Next for Microsoft Edge?

This security update is one of the final enhancements for the current version of Edge. Following this, Microsoft is set to launch Edge version 139 next week, which is presently in the Beta Channel. This upcoming version promises substantial additions, including improved WebUI 2 components aimed at boosting performance, real-time notifications for compromised passwords, and updates to the Edge Wallet, among other enhancements.

Market Trends and User Adoption

Despite the steady influx of updates and features, including the newly revealed Copilot Mode, Microsoft Edge continues to struggle against Google Chrome in terms of user adoption. Recent statistics from Statcounter indicate a notable decline in Edge’s user base, while Chrome’s market share continues to expand, solidifying its dominance in the browser arena.
