Google Patches 3rd Zero-Day Exploit in Chrome


Google has been having quite a week because it just patched its third zero-day vulnerability in Chrome within seven days. The latest culprit? CVE-2024-4947.

If you think that sounds technical, you’re right, but stick with me. This affects almost everyone using the internet, so it’s worth unpacking

TL;DR Version: CVE-2024-4947 is a zero-day vulnerability in Chrome that’s being actively exploited. This makes it the third vulnerability that has been fixed in Chrome within the past week.

In layman’s terms, zero-day means the folks exploiting it found the vulnerability before Google could patch it. Yikes.

The Official Statement from Google

Google dropped this bombshell in its official blog: “The Stable channel has been updated to 117.0.5938.132 for Windows, Mac, and Linux, which will roll out over the coming days/weeks.”

Yup, they’re basically saying update your browser ASAP to avoid falling prey to these exploits because they are, in fact, being used on the greater public right now.

The Chain of Events

The first zero-day, CVE-2024-4868, was also raised a ruckus earlier in the week followed closely by CVE-2024-4946. And now, CVE-2024-4947 completes this hat-trick of headaches for Google’s security team.

Dive Deeper: What is CVE-2024-4947? According to Bleeping Computer, this Zero-day revolves around an exploit discovered in Chrome’s Rendering Engine, which is a pretty key part of the browser.

This exploit has been used actively in the wild, meaning bad actors have been taking advantage of it while the rest of us were blissfully unaware.

Why Should You Care?

These vulnerabilities can be used for everything from stealing personal information to deploying ransomware. Not updating your browser is akin to locking your front door but leaving the window open.

Protecting Yourself: To update to Chrome, go to your Chrome settings and update to version 117.0.5938.132.
