Google Issues Emergency Chrome Update to Patch Critical Remote Code Execution Flaw
Google Issues Emergency Chrome Update to Patch Critical Remote Code Execution Flaw
Google has released an emergency security update for the Chrome browser on all platforms, addressing five vulnerabilities — including a critical flaw that could allow remote code execution (RCE). The patch is rolling out now as versions 142.0.7444.134 and 142.0.7444.135 for Windows, Mac, and Linux users.
Why This Update Matters
The urgent release targets multiple vulnerabilities discovered in Chrome’s WebGPU implementation, as well as its Views and V8 JavaScript components — all potential gateways for attackers to compromise user systems remotely.
While the update began rolling out on November 5, 2025, Google confirmed that full deployment may take several days to reach all users. The company is restricting detailed vulnerability information until most devices have been patched, a standard security measure to prevent active exploitation during rollout.
The Critical WebGPU Vulnerability: CVE-2025-12725
The most severe issue patched is CVE-2025-12725, a high-severity out-of-bounds write flaw found in Chrome’s WebGPU subsystem.
Initially reported on September 9, 2025, this vulnerability allows malicious web content to manipulate memory beyond its intended boundaries — a technique that can lead to full remote code execution on unpatched systems.
In simpler terms, this flaw could let attackers run arbitrary code just by getting a user to visit a compromised website — no downloads, no clicks required.
Additional High-Severity Vulnerabilities
Google also patched:
CVE-2025-12726 — A flaw in Chrome’s Views component, responsible for rendering and managing the user interface. This vulnerability poses a major risk because it impacts the way Chrome handles window management and rendering, potentially enabling sandbox escapes.
CVE-2025-12727 — A serious issue within the V8 JavaScript engine, discovered by researcher 303f06e3 on October 23, 2025. Since V8 executes all JavaScript code in Chrome, any exploit here could allow attackers to inject and execute malicious scripts directly through web pages.
Two medium-severity flaws — CVE-2025-12728 and CVE-2025-12729 — were also addressed in Chrome’s Omnibox (search and navigation bar). Although less severe, both flaws could still allow manipulation of browser behavior or limited data exposure.
Cross-Platform Coverage
This emergency update applies to:
Windows: Chrome 142.0.7444.134 and 142.0.7444.135
Mac: Chrome 142.0.7444.134
Linux: Chrome 142.0.7444.134
Android: Security fixes via Google Play (rolling out this week)
iOS: Chrome Stable version 142.0.7444.128 (released November 4, 2025)
Google’s Security Response
To catch and mitigate these flaws before they could be weaponized, Google employed multiple detection tools — including AddressSanitizer, MemorySanitizer, and fuzzing technologies.
The Chrome security team continues to collaborate with independent researchers and encourages new vulnerability submissions through its bug bounty program to sustain proactive defense against browser-based threats.
