Google Chrome 0-Day Vulnerability Under Active Exploitation

Google has rolled out Chrome 138 (138.0.7204.157) for Android devices, marking a significant stability and security-focused update that addresses multiple vulnerabilities and performance issues.

This release, announced on Tuesday, July 15, 2025, is part of a coordinated cross-platform update that includes corresponding desktop versions for Windows, Mac, and Linux systems.

Addresses Critical Vulnerabilities

The latest Android update incorporates the same security fixes deployed across Chrome’s desktop counterparts, ensuring platform parity in vulnerability mitigation.

The security enhancements include patches for several high-severity Common Vulnerabilities and Exposures (CVEs), most notably CVE-2025-7656, an integer overflow vulnerability in the V8 JavaScript engine that carried a $7,000 bounty reward.

Additionally, the update addresses CVE-2025-6558, a high-severity flaw involving incorrect validation of untrusted input in ANGLE and GPU components, for which Google has confirmed active exploitation in the wild.

The security fixes also encompass CVE-2025-7657, a use-after-free vulnerability in WebRTC that could potentially allow remote code execution.

These vulnerabilities were identified through Google’s comprehensive security research program, which utilizes advanced detection tools including AddressSanitizer, MemorySanitizer, UndefinedBehaviorSanitizer, Control Flow Integrity, libFuzzer, and AFL fuzzing technologies.

Performance Optimization and Stability Improvements

Beyond security enhancements, Chrome 138.0.7204.157 for Android delivers substantial performance improvements and stability fixes.

The update leverages Google’s internal auditing processes and fuzzing initiatives to identify and resolve potential issues before they impact end users.

The Git log provides comprehensive documentation of all implemented changes, offering developers and security researchers detailed insights into the update’s scope.

The rollout strategy employs a gradual deployment mechanism through the Google Play Store, ensuring controlled distribution over the coming days to minimize potential disruption while allowing for rapid issue identification and resolution.

This approach aligns with Google’s established update methodology for maintaining system stability across its vast Android user base.

Cross-Platform Synchronization and Future Development

The Android update synchronizes with broader Chrome ecosystem improvements, including iOS version 138.0.7204.156 and ChromeOS updates spanning multiple channels.

This coordinated release strategy ensures consistent security posture and feature parity across all Chrome implementations.

Google encourages users experiencing issues to utilize the official bug reporting system, while the community help forum remains available for general support and troubleshooting.

The Chrome Release Team continues monitoring deployment metrics and user feedback to inform future development cycles and security enhancements.

Users can expect automatic update delivery through Google Play Store, with manual checking available through the application’s settings menu for immediate installation access.
