Chrome zero-day CVE-2026-2441 actively exploited, patch available
- Engineer — Act: CISA KEV listed, EPSS 0.55, public PoC, and active exploitation combine to demand immediate action. Update all Chrome and Chromium-based installations (including Electron apps and Chromium in CI/CD pipelines) to the latest stable channel release now.
- SOC/IR — Act: Active zero-day exploitation with public PoC means attacker tooling is already circulating. Hunt for suspicious child processes spawned by Chrome since early February, and tune EDR rules to flag anomalous browser subprocess activity consistent with renderer exploitation.
- Leader — Act: A CISA KEV-listed zero-day in the most widely deployed enterprise browser with confirmed in-the-wild exploitation warrants same-week confirmation. Verify that endpoint management has initiated an emergency Chrome patch cycle and confirm patch coverage metrics before end of week.
