Case Study on CVE-2025-12036 – Remote Code Execution in Google Chrome’s V8 JavaScript Engine #14
Description
We all think of Google Chrome as a safe and reliable browser that protects us when we go online. But even the most trusted software can have serious flaws. On October 24, 2025, a major bug was found in Chrome’s V8 JavaScript engine, which is the part that runs all the JavaScript and WebAssembly code inside the browser. This bug allows remote code execution by causing a memory corruption error, meaning an attacker could make your browser run harmful code just by visiting the wrong website. Since V8 is used in almost every Chromium-based browser, this issue could affect millions of people around the world.
Because of how important this vulnerability is, I want to write a MITRE Secure Coding Case Study on CVE 2025 12036. In my case study, I will explain how this vulnerability happened, how attackers could use it through malicious web content, and what developers can do to stop similar memory safety problems from happening again in engines like V8.
This case study will help software engineers, browser developers, and security researchers see how even one small coding mistake in a large system can lead to serious consequences. By explaining how the memory corruption worked and how Google fixed it, I want to share practical lessons about safer coding habits such as using secure programming languages, better automated testing and fuzzing, stronger sandboxing, and faster patch releases. My goal is not just to explain what went wrong but to show how these lessons can make future browsers and runtime systems safer for everyone
