Google has released Chrome 143 to the stable channel, addressing 13 security vulnerabilities that could allow attackers to execute arbitrary code on affected systems.
The update is now rolling out to Windows, Mac, and Linux users worldwide.
The latest version, Chrome 143.0.7499.40 for Linux and Chrome 143.0.7499.40/41 for Windows and Mac, brings essential security fixes along with various improvements.
Users are strongly encouraged to update their browsers immediately to protect against potential attacks.
Critical Security Fixes
The update addresses four high-severity vulnerabilities, including a dangerous type confusion bug in Chrome’s V8 JavaScript engine.
| CVE ID | Severity | Component | Description |
| CVE-2025-13630 | High | V8 | Type Confusion |
| CVE-2025-13631 | High | Google Updater | Inappropriate Implementation |
| CVE-2025-13632 | High | DevTools | Inappropriate Implementation |
| CVE-2025-13633 | High | Digital Credentials | Use After Free |
| CVE-2025-13634 | Medium | Downloads | Inappropriate Implementation |
| CVE-2025-13720 | Medium | Loader | Bad Cast |
| CVE-2025-13721 | Medium | V8 | Race Condition |
| CVE-2025-13635 | Low | Downloads | Inappropriate Implementation |
| CVE-2025-13636 | Low | Split View | Inappropriate Implementation |
| CVE-2025-13637 | Low | Downloads | Inappropriate Implementation |
| CVE-2025-13638 | Low | Media Stream | Use After Free |
| CVE-2025-13639 | Low | WebRTC | Inappropriate Implementation |
| CVE-2025-13640 | Low | Passwords | Inappropriate Implementation |
This flaw could allow attackers to run malicious code on victims’ computers. Google paid $11,000 to the researcher who discovered this issue.
The most serious flaw is the type confusion bug in V8. Type confusion occurs when the browser mishandles data, creating opportunities for attackers to take control of a system.
Two “use after free” vulnerabilities were also patched. These occur when the browser tries to use memory that has already been released, potentially allowing code execution.
Several “inappropriate implementation” issues were fixed across different components, including DevTools, Downloads, and WebRTC.
Chrome typically updates automatically. To manually check for updates:
- Open Chrome
- Click the three-dot menu
- Go to Help > About Google Chrome
- Chrome will check for and install updates
Google thanked all security researchers who reported these issues. The company uses tools such as AddressSanitizer, MemorySanitizer, and libFuzzer to detect security bugs before they reach users.
Users who discover new security issues can report them through Google’s bug reporting system. The Chrome community forum is available for those needing help with browser issues.
