About this tag
The chromium side-channel tag covers information leaks in Chromium-based browsers like Microsoft Edge, focusing on side-channel attacks that exploit timing or resource measurements. A key example is CVE-2026-3929, a medium-severity ResourceTiming side-channel that leaks data without crashing the browser. These flaws are inherited from upstream Chromium code, meaning fixes come through Google's security updates and are ingested by Microsoft for Edge. Discussions emphasize the subtle nature of side-channel vulnerabilities, which differ from remote code execution bugs, and the importance of keeping browsers updated to mitigate such risks.
