Google Chrome: security update for versions 152.0.7977.82/83
Google has released a security update for Chrome that addresses twelve vulnerabilities, including a zero-day flaw. The flaw in question, identified under the code CVE-2026-85046, affects the browser’s V8 JavaScript engine. This issue was reported by Salvatore Gulizia, a researcher who was awarded $1,000 for his discovery.
This patch is now available for Windows, macOS, and Linux users. It is highly recommended to install this update to protect against potential attacks. Users can update their browser by going to the Chrome menu, under Help, then About Google Chrome.
Vulnerability CVE-2026-85046: a serious threat
The CVE-2026-85046 vulnerability has a CVSS score of 8.8, highlighting the severity of the flaw. It allows a remote attacker to execute arbitrary code from a simple malicious HTML page. The problem stems from an error in V8 compilers, creating confusion between data types, allowing unauthorized access to certain areas of memory.
This flaw is the sixth zero-day fixed in Chrome this year, underscoring the importance of remaining vigilant against cybersecurity threats.
Nine other high-severity flaws fixed
In addition to the zero-day flaw, the update fixes nine other high-severity vulnerabilities, including another in V8 related to a race condition. Other flaws affect several Chrome components such as Compositing, WebGL, DevTools, Skia, and CacheStorage.
Two medium-severity flaws were also fixed, one related to incorrect input validation and the other to the use of a resource that had already been freed.
Impact on Chromium-based browsers
Chromium-based browsers, such as Microsoft Edge, Brave, Opera, and Vivaldi, will also need to apply their own patches as soon as they are available to ensure the security of their users.
Impact of security flaws on the cybersecurity world
These incidents once again highlight the importance of cybersecurity in our digital world. Companies like Google must constantly monitor and fix security flaws to protect user data. Security researchers, such as Salvatore Gulizia, play a crucial role in identifying these vulnerabilities and helping to fix them before they are widely exploited.
Cyberattacks are becoming increasingly sophisticated, and the ability to respond quickly to new threats is essential to prevent major security incidents. Users must also stay informed and apply security updates as soon as they are available to minimize risks.
FAQ on Chrome vulnerabilities
What is a zero-day flaw?
A zero-day flaw is a vulnerability that is exploited by hackers before the software developer is aware of it or has released a patch. This means there is no time to fix the flaw before it is exploited.
How can I protect my Chrome browser?
To protect your Chrome browser, make sure it is always up to date. You can check for available updates by going to the Chrome menu, under Help, then About Google Chrome.
Which browsers are based on Chromium?
Chromium is the open-source base for several popular browsers, including Google Chrome, Microsoft Edge, Brave, Opera, and Vivaldi. These browsers benefit from the same security updates as Chrome but must apply them individually.
Why is browser security important?
Browser security is crucial because they are the main interface between the user and the Internet. A security flaw in a browser can potentially expose users to attacks, compromising their personal data and online privacy.
