There are moments in the tech world when an update is not just another routine patch running quietly in the background — it’s a warning, a signal that something urgent is happening behind the scenes. This week’s Google Chrome update falls exactly into that category. Instead of the usual calm rollout, this one arrived with a clear and pressing message: update your browser immediately.
If you’re using Chrome on Windows, macOS, or Linux, a significant fix has just been delivered under version 143.0.7499.110 (or 143.0.7499.0.110 depending on the sub-build). And unlike typical patches, this update addresses a security flaw that is not theoretical or under study — it’s actively being exploited in the wild.
Before we explore what happened, let’s take a moment to walk through what this update means, why it matters, and how to make sure you are protected.
Confirming Your Chrome Version
Every important update begins with a simple check. But instead of jumping straight into the steps, it helps to understand why this moment matters.
Recent Chrome patches have been frequent, but Google rarely highlights one with such urgency unless a genuine threat is already out there. When you update today, you are not just installing new code — you are closing a door that someone is already trying to open.
How to Check Your Chrome Version
Now let’s walk through the steps without skipping anything:
- Open Google Chrome.
- Click the three-dot menu at the top-right corner.
- Go to Help → About Google Chrome.
- Chrome will automatically check for updates.
- Your browser should display:
Version 143.0.7499.110 (or 143.0.7499.0.110) - Wait until the update finishes downloading and applying.
- Click Relaunch if Chrome asks for it.
If you see Version 143.x, your browser is fully patched and secure for this update cycle.

Understanding Why This Update Is Critical
Before diving deeper, let’s set the scene. When Google flags something as a zero-day, it means attackers have already discovered a weakness before Google or the public gets a chance to react. Unlike theoretical vulnerabilities that may never be used, zero-days often appear in real attacks — sometimes quietly, sometimes aggressively.
This patch resolves such an issue. And interestingly, Google has taken a slightly unusual approach this time, providing no CVE number yet.
A Zero-Day Without a CVE — Why This Silence?
Your script mentions something important: Google revealed that it is aware of an exploit for 466192044 that “exists in the wild.”
But they have not assigned a CVE ID, which is rare.
There are usually only two reasons why this happens:
1. Internal Coordination Is Still Ongoing
Different security teams — both at Google and possibly external partners — may still be piecing together the full attack chain.
Premature disclosure could lead to confusion or incorrect analysis.
2. Google Is Holding Back Details to Prevent Abuse
Sometimes the safest thing Google can do is to stay quiet until enough users have patched their browsers.
If attackers learn the specifics before the majority of Chrome installs are updated, the threat could escalate dramatically.
In short, the silence is intentional. The vulnerability is active, and Google wants the world patched before it gives attackers a detailed map.
What the Update Fixes — A Closer Look
So far, Google has confirmed three fixes inside this update:
1. A High-Severity Zero-Day Exploited in the Wild
This is the one labeled 466192044.
Although we don’t have the CVE or technical details yet, the “exploited in the wild” tag tells us everything we need:
this is already being used by attackers, not tested in a lab.
2. A Medium-Severity Vulnerability: Use-After-Free in Password Manager
This type of flaw is especially concerning because Chrome’s password manager holds sensitive credentials.
A use-after-free bug allows attackers to manipulate memory in ways that could lead to code execution, crashes, or data exposure.
3. Another Medium-Severity Issue: Inappropriate Implementation in Toolbars
While less severe, improper implementation can still open up ways to bypass certain restrictions or trigger unexpected behavior.
Together, these fixes make this update one of the most important weekly patches in recent months.
What About uBlock Origin and MV2 Extensions?
Let’s pause for a moment because your script raises a question many users silently have:
Did this update break uBlock or the MV2 workaround?
The good news is simple:
No — the workaround still functions, and uBlock Origin still works properly even after installing Chrome version 143.
This confirms that Google did not use this update to disable MV2 or privacy extensions; their focus was entirely on security.
If you rely on ad-blocking to make your browsing faster, cleaner, or distraction-free, nothing changes today.
What About Other Chromium Browsers?
Every time Chrome receives an emergency patch, the natural follow-up question is whether Brave, Microsoft Edge, Opera, Vivaldi, and others will follow.
Since this is a Chromium-level zero-day, the underlying engine is affected, not just Chrome itself.
That means:
- These browsers will also receive updates.
- The updates will likely roll out very soon — sometimes within hours or a couple of days.
If you use these browsers, keep an eye on their update pages:
- Edge — https://learn.microsoft.com/en-us/deployedge/microsoft-edge-relnote-stable-channel
- Brave — https://brave.com/latest/
- Opera — https://blogs.opera.com/desktop/
Why You Should Update Immediately
Even though most browser updates feel routine, a zero-day is different.
You’re not patching a hypothetical weakness — you’re stopping an attack that might be targeting users right now.
Updating today protects:
- Your saved passwords
- Your browsing sessions
- Your synced data
- Your work and personal logins
- Your everyday privacy
Chrome typically applies updates silently, but zero-day fixes deserve manual confirmation.
This is one of those times.
