New Chrome Vulnerability Could Let Hackers Escape Browser Security – What You Need to Know
A newly discovered security flaw in Google Chrome is drawing serious attention from cybersecurity experts around the world, and Nigerians using Chrome browsers are advised to take immediate action by updating their browsers.
The issue, discovered in the browser's graphics handling system, has already been exploited by attackers online—making it a real threat to users. The flaw is associated with Chrome's rendering engine and its interaction with GPU hardware, which can allow malicious actors to bypass built-in browser protections and execute code outside the browser sandbox.
This type of vulnerability is especially dangerous because attackers can trigger it just by tricking users into visiting a malicious website. No downloads or clicks are required—the compromise happens in the background, silently and instantly.
What’s the Risk?
This specific flaw lies in Chrome’s ANGLE (Almost Native Graphics Layer Engine), a component that translates browser rendering tasks into commands that the underlying graphics hardware can understand. If this process is not properly secured, attackers can exploit the low-level GPU instructions to escape the browser sandbox. The sandbox is designed to isolate code execution from the rest of the system, preventing malware from accessing sensitive files or system resources.
When a sandbox escape occurs, the attacker may gain privileges beyond the browser itself—opening the door to spying, data theft, or installation of malware. This vulnerability allows remote attackers to craft a special HTML page that exploits this weakness, turning the browser into a launchpad for further attacks.
Who Found It?
The issue was identified by researchers from Google’s Threat Analysis Group (TAG), who specialize in investigating government-backed hacking and advanced persistent threats (APT). The fact that the flaw was discovered by this particular team suggests it may have been used in highly targeted attacks, possibly involving nation-state actors.
Although Google hasn’t released full technical details, the company confirmed that the vulnerability is being actively used in real-world attacks. This marks yet another instance in a growing trend of high-severity Chrome zero-day vulnerabilities being discovered and patched mid-year.
Similar Issues in the Past
This incident follows another zero-day vulnerability fixed just weeks prior. Google has already patched at least five high-impact flaws in Chrome this year alone, many of which were considered critical. These types of vulnerabilities are often linked to bugs in graphics rendering, memory management, and privilege boundary violations—key areas of concern for browser developers and security teams alike.
While Chrome is the main focus, it's important to understand that other Chromium-based browsers, including Microsoft Edge, Brave, Opera, and Vivaldi, also share much of the same codebase. This means they are potentially vulnerable to similar attacks until they release their own patches.
What Should Users Do?
Nigerian users, especially those handling sensitive data such as in banking, government, education, and tech, should prioritize updating their Chrome browser immediately. The patched versions—138.0.7204.157 and above—are now available for Windows, macOS, and Linux platforms.
To update:
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 install the latest version.
Click Relaunch to complete the update.
If you're using other browsers like Edge or Brave, ensure you're using the most recent version or check for security updates from the official sources.
Stay Secure
Cyber threats are evolving fast, and browser exploits like this demonstrate how even everyday activities like browsing the web can become risky. Keeping your browser updated, avoiding suspicious links, and using a reputable antivirus solution are essential steps for staying protected.
For cybersecurity professionals, this case is another reminder that GPU and rendering-related vulnerabilities are gaining traction among attackers and should be monitored closely in future research and assessments.
