A use after free in Chromium's CSS handling with an unusually high 22% EPSS for a browser bug, and confirmed exploitation via its February 17, 2026 CISA KEV entry. CSS is parsed on every page load, so the attack surface is unavoidable: any site or ad frame a user visits can attempt the trigger. High Severity (CVSS 8.8) across all Chromium-based browsers, Microsoft Edge included.
