Google has released an emergency security update for its Chrome browser to address a critical zero-day vulnerability that is already being exploited by hackers. A zero-day flaw is so named because it is a previously unknown security vulnerability that is actively exploited by hackers before the vendor becomes aware of it or has time to create a fix. The flaw is described as a “Use-After-Free” vulnerability within the Google Chrome rendering engine.

While Chrome users receive the update directly from Google, those using other Chromium-based browsers may still be at risk.
