Google Chrome Vulnerabilities

According to a new security advisory by CERT-In, Google Chrome versions prior to 141.0.7390.54/55 for Windows, Mac, and Linux are affected by multiple security flaws. These issues could allow attackers to execute arbitrary code, bypass security protections, or trigger denial-of-service (DoS) attacks on a victim’s computer. news Also Read: “This Is How Cybercrime Begins”: Akshay Kumar Shares Shocking Daughter’s Online Gaming Incident

In simpler terms, if you’re running an older version of Chrome and happen to land on a malicious website, an attacker could exploit these weaknesses to take control of your browser—or worse, gain access to your data. news Also Read: Google Chrome Gets AI Boost!

The flaws have been linked to issues like heap buffer overflow in WebGPU and Video, side-channel information leaks in Storage and Tabs, and “use-after-free” errors in Chrome’s V8 engine, which powers JavaScript.

Google has already pushed a fix with the release of Chrome version 141.0.7390.54 for Linux and 141.0.7390.54/55 for Windows and Mac, which includes 21 security patches. The company says the update will roll out over the coming days and weeks. You can manually check for updates by going to Settings, clicking About Chrome, and selecting Update Chrome.

Mozilla Firefox Also Affected

Mozilla has also confirmed multiple vulnerabilities in Firefox for both iOS and desktop platforms. The affected versions include Firefox for iOS prior to 143.1 and Firefox desktop versions prior to 143.0.3.

These vulnerabilities are caused by improper isolation of cookie storage, integer overflow in the Graphics Canvas2D component, and JIT miscompilation in the JavaScript Engine. If exploited, attackers could perform remote code execution or access sensitive data—essentially compromising your system or personal information.

It must be noted that Mozilla has released patched versions of Firefox to fix these issues. Users are urged to update their browsers right away through the app store (for iOS) or the browser’s settings menu (for desktop).
