Google late Thursday night shipped an emergency patch to close a Chrome browser vulnerability that was being used in mysterious zero-day attacks.
The Google Chrome patch, which is being pushed via the browser’s automatic self-patching, covers a critical vulnerability in V8, Google’s JavaScript and WebAssembly engine.
The “high-risk” vulnerability affects users on Windows, MacOS and Linux platforms.
