If you’ve been hitting “Remind me later” on that Chrome update, now’s the time to stop. Google just rolled out a critical security patch that addresses three newly discovered vulnerabilities — the kind that could let hackers crash your browser, steal your data, or even take remote control of your system. So yes, it’s serious.
Chrome hit by three high-risk bugs
The flaws were flagged by independent security researchers through Google’s bug bounty program, which rewards experts for finding potential threats before criminals do. While none of these have been exploited in the wild — yet — they’re serious enough for Google to act fast and stay tight-lipped about the details until most users are protected.
According to the company, the vulnerabilities affect key components of Chrome that manage syncing, local storage, and media content — all core features millions of users rely on daily.
What the flaws could do if left unpatched
The first vulnerability lies in Chrome’s Sync system, which keeps your bookmarks, passwords, and browsing history in sync across devices. In the wrong hands, it could be exploited to crash your browser remotely, corrupt synced data, or run unauthorized code — a perfect setup for more advanced attacks if chained with other weaknesses.
The second issue targets Chrome’s local storage handler. Under certain conditions, Chrome attempts to access memory that has already been released — a classic memory management bug that opens the door to potential data theft or malicious code execution.
The third flaw, while less severe, affects Chrome’s WebCodecs component — the system responsible for processing audio and video inside the browser. It could allow an attacker to read sensitive data from Chrome’s memory, especially when media content is involved.
Install the update now to stay protected
To fix all three vulnerabilities, Google has released version 141.0.7390.65/.66 of Chrome for Windows and macOS, and 141.0.7390.65 for Linux. If you’re not sure whether your browser is up to date, here’s how to check:
- Open Chrome
- Click the three-dot menu in the top-right corner
- Go to Help > About Google Chrome
- Chrome will automatically check for updates and prompt you to Restart
It’s also a good idea to turn on automatic updates if you haven’t already. Regular restarts ensure new security fixes take effect immediately.
A reminder: security starts with updates
These flaws are a stark reminder of how vital it is to keep your software updated — especially browsers, which are constantly exposed to the internet’s more shadowy corners. With Google working to stay ahead of attackers, the least we can do is click “Update” when prompted.
So if you haven’t done it yet, stop what you’re doing and update Chrome. It’s quick, it’s free, and it just might save your data — or your whole device — from being compromised.
