vulnerability analysis and mitigation
Overview
A high-severity zero-day vulnerability identified as CVE-2025-6554 was discovered in Google Chrome's V8 JavaScript and WebAssembly engine. The vulnerability was reported by Clément Lecigne of Google's Threat Analysis Group on June 25, 2025, and was patched in Chrome version 138.0.7204.96. This type confusion flaw allowed remote attackers to perform arbitrary read/write operations through a specially crafted HTML page (Chrome Release, Hacker News).
Technical details
The vulnerability is classified as a type confusion flaw (CWE-843) in Chrome's V8 engine, receiving a CVSS v3.1 base score of 8.1 (High). Type confusion vulnerabilities can lead to unexpected software behavior, potentially resulting in arbitrary code execution and program crashes. The issue was quickly mitigated on June 26, 2025, through a configuration change pushed to the Stable channel across all platforms (NVD, Hacker News).
Impact
The vulnerability affects Chrome browsers across multiple platforms, including Windows (versions prior to 138.0.7204.96/.97), macOS (versions prior to 138.0.7204.92/.93), and Linux (versions prior to 138.0.7204.96). When exploited, the flaw could allow attackers to execute arbitrary code, install spyware, launch drive-by downloads, or run malicious code silently, potentially triggered by simply visiting a malicious website (Hacker News).
Mitigation and workarounds
Users are strongly advised to update their Chrome browser to the latest version: 138.0.7204.96/.97 for Windows, 138.0.7204.92/.93 for macOS, and 138.0.7204.96 for Linux. The update can be applied by navigating to Settings > Help > About Google Chrome. Users of other Chromium-based browsers (Microsoft Edge, Brave, Opera, and Vivaldi) should also apply updates when available (Hacker News).
Community reactions
This marks the fourth zero-day vulnerability in Chrome addressed by Google in 2025, following CVE-2025-2783, CVE-2025-4664, and CVE-2025-5419. The rapid response from Google, implementing a configuration change within a day of discovery, demonstrates the company's commitment to addressing critical security issues (Hacker News).
