Google has released an urgent security update for its Chrome web browser to patch a critical use-after-free vulnerability.
This vulnerability is tracked as CVE-2025-9478 (no CVSS score yet, but classified as "critical" by Google), is a security flaw in the ANGLE graphics library that could enable attackers to execute arbitrary code on vulnerable systems through malicious web pages. The ANGLE (Almost Native Graphics Layer Engine) component is a translation layer between Chrome's rendering engine and device-specific graphics drivers. The flaw enables program code to accesses resources that have already been released and have undefined content, creating opportunities for memory corruption and potential system compromise.
The vulnerability affects all Google Chrome versions prior to the patched releases on all platforms.
Google released the security patches as part of Chrome Stable versions 139.0.7258.154/.155 on Windows and macOS, and 139.0.7258.154 on Linux on Tuesday, August 26, 2025.
Users can verify their Chrome version and trigger manual updates by navigating to the menu icon (three stacked dots), selecting "Help," then "About Google Chrome." The browser will automatically check for and install available updates. On Linux systems, users may need to use their distribution's package management system to receive the update.
