For the third time this year, Google has shipped an urgent fix to block in-the-wild zero-day attacks hitting its flagship Chrome browser.

The latest emergency Chrome patch, available for Windows, MacOS and Linux, provides cover for at least five documented vulnerabilities.

It is the third in-the-wild zero-day attack hitting Chrome users in 2021, and in all three cases, Google has been stingy with information on the malware used, the OS platforms targeted or the indicators of compromise that help enterprise defenders.

The North Korean state-sponsored hacks against security researchers, Google has barely confirmed the existence of the Chrome zero-day with a one-line mentioned that fully-patched Chrome installations were being compromised.

Simply as a use-after-free vulnerability in Chrome's Blink rendering engine that was anonymously reported to Google.

The Chrome patch is being pushed to Chrome users via the browser's automatic updating mechanism but users are urged to restart browser sessions to properly apply the fixes.
