What's new in Google Chrome
Chrome adds Gemini AI‑based protection
Google Chrome now uses a Gemini‑powered on‑device AI model to spot fraud and ClickFix attacks when Enhanced Protection is turned on.
- Available to users who enable Chrome’s Enhanced Protection feature, which is optional in the browser’s security settings.
- The AI scans page text for scam indicators and monitors clipboard content for suspicious command‑line scripts.
- If a risky command is detected, Chrome scrubs personal data, sends the payload to Safe Browsing for analysis, and shows a warning before the user can paste it.
- Chrome also classifies sites as “Suspicious” or “Dangerous” and adds financial‑services ad verification in the U.S. and Canada.
For Chrome users, this means an extra layer of defense against social‑engineering tricks that bypass traditional download filters, especially those that try to get you to run malicious commands in the terminal. If you rely on Chrome for everyday browsing and want stronger protection against emerging scams, enabling Enhanced Protection is a sensible step; otherwise, you may prefer a browser that offers similar AI‑driven safeguards out of the box.

What changed
The new Chrome build addresses 37 security issues spanning memory handling, JavaScript, PDF processing, networking, SVG graphics, media, and core browser functions. Highlights include:
- A critical buffer‑overflow bug in ANGLE (CVE‑2026‑110152) that could cause crashes or code execution.
- Six critical use‑after‑free flaws affecting PDF files, networking, SVG, media and core components.
- High‑severity problems in the V8 engine, password manager, extensions, WebRTC, DOM, PDFium and Canvas, including CVE‑2026‑110169.
These flaws could let attackers run unauthorized code, steal data, gain higher privileges, or disrupt services.
Who gets it and when
The update is being pushed to all Chrome desktop installations that are on versions earlier than 155.0.8059.79 for Linux and earlier than 155.0.8059.79/155.0.8059.80 for Windows and macOS. Google rolls out patches in stages, so some users may see the new version a few days after the initial release.
How to use it
To verify you have the patched version:
- Open Chrome and click the three‑dot menu in the upper‑right corner.
- Select Help > About Google Chrome.
- The browser will automatically check for updates and begin downloading if a newer build is available.
- Restart Chrome when prompted to complete the installation.
If the update does not appear immediately, give it a day or two as Google continues the staged rollout.
What it means if you are choosing Google Chrome
For most users, the patch restores confidence that Chrome’s security model remains robust. The breadth of fixes shows Google’s active response to critical bugs, especially in components like V8 and ANGLE that are frequent attack targets.
However, the need for frequent high‑severity patches may be a signal for security‑focused organizations to evaluate alternatives that emphasize rapid update cycles or additional hardening. Two notable options are:
- Microsoft Edge – also built on Chromium, it receives similar security updates and may suit Windows‑centric environments.
- Mozilla Firefox – an open‑source browser with a separate code base, offering a different security architecture.
Choosing Chrome still makes sense for users who value its extensive extension ecosystem, tight integration with Google services, and familiar UI, provided they keep the browser up to date.
FAQ
Is the update automatic?
Yes. Chrome checks for updates in the background and downloads them without user intervention, though a manual restart may be required.
Do mobile Chrome versions need the same patch?
The source only references desktop builds for Windows, macOS and Linux. Mobile versions were not mentioned, so users should check their device’s update settings separately.
What should I do if the update doesn’t appear?
Give the staged rollout a few days, then revisit the About page. If it still doesn’t show, you can manually download the latest installer from Google’s official Chrome download page.
Bottom line
Google’s October 2026 Chrome update patches a large set of critical and high‑severity bugs, reinforcing the browser’s security posture. Users should verify they have the new version via the About page and restart Chrome to apply it. While Chrome remains a solid choice for most, security‑conscious users may also consider Edge or Firefox as viable alternatives.
