CVE-2025-2137 is a crucial security vulnerability affecting Google Chrome versions prior to 134..6998.88. This vulnerability is caused by an out of bounds read in the V8 JavaScript engine, a core component of Google Chrome. The Chromium project has classified the security severity of this issue as medium. A remote attacker could exploit this vulnerability to perform out of bounds memory access by utilizing a specially crafted HTML page.

Description and Exploit Details

An out of bounds read vulnerability exists within the V8 engine used by Google Chrome, which allows attackers to access memory regions located beyond the allocated boundaries. This may lead to arbitrary code execution or information disclosure on the victim's machine. The V8 engine is responsible for executing JavaScript code in the Chrome browser, making it a prime target for attackers who want to exploit browser vulnerabilities.

To exploit this vulnerability, an attacker would need to create a malicious HTML page containing specially crafted JavaScript code. The attacker would then need to trick the victim into visiting the page, either by sharing it through email or other messaging platforms or embedding the malicious content into a legitimate website.

When the victim views the malicious HTML page, the vulnerable V8 engine accesses memory outside the intended boundary. This allows the attacker to read or potentially modify data located in the memory of the victim's machine, leading to various adverse consequences, including unauthorized access to sensitive information and potential code execution.

Here's a simple proof of concept to demonstrate the vulnerability in action

<!DOCTYPE html>
<html>
<head>
  <script>
    function triggerVuln() {
        // Specially crafted JavaScript code to exploit the vulnerability
    }
  </script>
</head>
<body onload="triggerVuln();">
  <!-- The malicious page content -->

  <p>Exploiting CVE-2025-2137...</p>
</body>
</html>

As seen in the code snippet, the triggerVuln() function will contain the malicious JavaScript code that exploits the vulnerability when the page gets loaded.
