The update arrived on November 11, 2026, just two days after Google released an earlier Chrome security patch addressing an actively exploited zero-day vulnerability. The latest release covers Chrome desktop versions 157.0.8103.78 for Linux and 157.0.8103.78/.79 for Windows and macOS. Google is distributing the update gradually over the coming days and weeks. According to Google's official Chrome Releases blog, all five critical vulnerabilities involve use-after-free memory errors. The remaining 78 vulnerabilities are classified as High severity. The rapid sequence of security releases highlights the importance of keeping web browsers updated, particularly when attackers are actively exploiting previously discovered weaknesses. ## Five Critical Vulnerabilities Affect Chrome The November 11 update addresses five vulnerabilities that Google has assigned its highest Critical severity rating. All five are classified as use-after-free vulnerabilities, a type of memory-management error that occurs when software continues to access memory after it has already been released. The affected Chrome components include: | CVE Identifier | Affected Component | Vulnerability | | --- | --- | --- | | CVE-2026-126885 | ServiceWorker | Use after free | | CVE-2026-126895 | CSS | Use after free | | CVE-2026-126879 | Layout | Use after free | | CVE-2026-126846 | Skia | Use after free | | CVE-2026-126911 | Accessibility | Use after free | These vulnerabilities affect different browser components responsible for background web tasks, page styling, layout rendering, graphics and accessibility. Use-after-free errors can potentially lead to memory corruption and other security problems. Their actual impact depends on the affected component and whether an attacker can successfully exploit the vulnerability. Google has not announced that these five newly patched critical vulnerabilities are being actively exploited in the wild. ## Chrome Fixes 83 Security Issues in One Release The latest Chrome Stable update contains 83 security fixes. The severity breakdown is: - **5 Critical vulnerabilities:** The highest severity classification. - **78 High-severity vulnerabilities:** Security weaknesses requiring serious attention. The reported issues cover several vulnerability categories, including use-after-free errors, buffer overflows, type confusion, out-of-bounds memory access and authorization problems. Google also credited external security researchers and its internal security teams for identifying and reporting vulnerabilities. Researchers associated with Anthropic and OpenAI were among those credited in the published security list. Google may restrict access to detailed vulnerability information until a sufficient number of users have installed the security update. This helps reduce the risk of attackers using technical details to target unpatched systems. ## Previous Chrome Update Fixed an Actively Exploited Zero-Day The latest security release follows another important Chrome update published on November 9, 2026. That earlier update fixed nine security vulnerabilities, including a high-severity zero-day tracked as **CVE-2026-125350**. Google confirmed that an exploit for this vulnerability existed in the wild, meaning attackers had already developed or used an exploit before the security patch was released. The vulnerability was identified as a use-after-free issue in Chrome's XML component. The November 9 release included these desktop versions: - Windows: 157.0.8103.50/.51 - macOS: 157.0.8103.50/.51 - Linux: 157.0.8103.50 Google's November 11 release then introduced another update, moving supported desktop platforms to version 157.0.8103.78/.79. The two releases demonstrate how quickly browser security updates can follow one another when new vulnerabilities require attention. ## How to Update Google Chrome Chrome users should install the latest available security update as soon as it reaches their devices. Follow these steps on a desktop computer: - Open Google Chrome. - Select the three-dot menu in the upper-right corner. - Navigate to **Help**. - Select **About Google Chrome**. - Allow Chrome to check for available updates. - Install the update if it is available. - Restart the browser to complete the installation. > Check the installed version under Chrome's About Google Chrome section. For Android users, open the Google Play Store, search for Google Chrome and install the available update. For managed business computers, administrators should verify the installed browser version through their organization's update-management tools. ## Why Browser Security Updates Matter Web browsers are among the most frequently used applications on computers and mobile devices. They process websites, scripts, images, videos, downloaded files and many other types of content. A vulnerability in a browser component can potentially expose users to security risks when they visit malicious or compromised websites. Keeping Chrome updated helps protect against known vulnerabilities and reduces the opportunity for attackers to exploit weaknesses that Google has already addressed. Users should also be careful when installing browser extensions. Extensions can request access to browsing data, website content and other sensitive information.

The timing is particularly notable because it follows an earlier update that fixed CVE-2026-125350, a zero-day vulnerability confirmed to have an exploit in the wild. Chrome users should check their browser versions, install the latest available updates and restart the browser. For businesses and IT administrators, the two releases also reinforce the importance of maintaining an effective browser patch-management process. ### Official Sources and References [Google Chrome Releases – November 11, 2026 Security Update](https://chromereleases.googleblog.com/2026/11/stable-channel-update-for-desktop_01744469280.html) [Google Chrome Releases – November 9, 2026 Zero-Day Update](https://chromereleases.googleblog.com/index.html) --- Original Source: https://www.mindstick.com/news/8010/chrome-update-fixes-83-vulnerabilities-including-5-critical-flaws Copyright © MindStick Software Pvt.
