Google addressed a critical use-after-free vulnerability in its Chrome browser that could potentially lead to code execution.
A researcher earned $43000 from Google for reporting a critical Chrome vulnerability, tracked as CVE-2025-10200, in the Serviceworker component.
A use-after-free (UAF) occurs when a program accesses memory after it has been freed. This can cause crashes, data corruption, or enable exploits like remote code execution. Common in C/C++ programs, UAFs are frequent in browsers and OS software handling manual memory management.
The researcher Looben Yang reported the vulnerability to Google on August 22, 2025.
Google rolled out a Chrome update that addressed this issue and another bug, tracked as CVE-2025-10201. CVE-2025-10201 is an inappropriate implementation in Mojo, which is an inter-process communication (IPC) framework used by Google Chrome.
Researchers Sahan Fernando and an anonymous expert reported the flaw CVE-2025-10201 and earned $30000 from Google for reporting this issue.
The Chrome update is being released as version 140.0.7339.127/.128 for Windows, 140.0.7339.132/.133 for macOS, and 140.0.7339.127 for Linux.
