Did the Latest Chrome Update Make Your Browsing Instantly Safer from Critical Flaws?
It is wise to keep your web browser updated. On October 28, 2025, Google released an important security update for its Chrome browser. This update fixes several serious problems. However, a separate, serious bug that causes browser crashes was found in a development version of Chromium, the foundation for many popular browsers.
Chrome’s Essential Security Update
Google updated the stable version of Chrome to keep you safe. The new versions are 142.0.7444.59/60 for Mac and Windows computers, and 142.0.7444.59 for Linux. Your browser likely updated itself automatically. You can always check by opening the Chrome menu and selecting “About Google Chrome” to confirm you have the latest version.
This update closes a number of high-risk and medium-risk security holes. Think of these as unlocked doors in your browser’s code. Attackers could potentially use them to cause harm. Google paid security researchers thousands of dollars for finding many of these flaws, which helps make the web safer for everyone.
The fixes address several kinds of issues:
- Engine Problems: Several flaws were fixed in V8, the core engine that runs the code on websites. These flaws could confuse the browser, leading to dangerous behavior.
- Memory Errors: The update corrects bugs where the browser might use memory improperly. Such errors, known as “Use after free” or “Object lifecycle issues,” can lead to crashes or allow an attacker to run malicious code.
- Rule Bypasses: Fixes were made to prevent websites or extensions from bypassing Chrome’s internal security rules.
A Serious Crashing Bug in Chromium
A security researcher discovered a critical bug in an unstable version of the Chromium browser project (version 143.0.7483.0). Google Chrome, Microsoft Edge, and many other browsers are built using Chromium’s code.
The researcher created a proof-of-concept called “Brash.” It shows how a specially crafted piece of code can crash most Chromium-based browsers within seconds. This type of flaw could be used to carry out denial-of-service attacks, which are designed to make a program or service unusable.
This crashing bug affects newer, non-stable versions of Chromium. The good news is that the official, stable version of Google Chrome that you get from the security update is not affected by this specific issue. Sticking with the stable, automatically updated version of your browser is the best way to protect yourself from these kinds of threats.
