Type Confusion Vulnerability in Google Chrome

CVE-2025-2135

What is CVE-2025-2135?

CVE-2025-2135 is a type confusion vulnerability found in the V8 JavaScript engine of Google Chrome, which is widely used as a web browser. This vulnerability occurs when the engine improperly manages types, leading to potential heap corruption when users interact with maliciously crafted HTML pages. Such an exploit could enable attackers to execute arbitrary code, presenting serious security risks that could impact organizational data and systems, making it crucial for users and organizations to remain vigilant.

Technical Details

The vulnerability is classified as a type confusion issue involving the V8 engine, which is responsible for executing JavaScript in the Chrome browser. Specifically, it affects versions of Chrome prior to 134.0.6998.88. By manipulating how types are handled within this engine, attackers can craft HTML pages designed to trigger this confusion, potentially leading to unintended code execution. Given that V8 is integral to Chrome’s functionality, any exploitation could disrupt normal operations and lead to severe outcomes.

Potential Impact of CVE-2025-2135

1. Remote Code Execution: The primary risk of CVE-2025-2135 is the possibility of remote code execution, allowing attackers to run malicious code on a user's system without their consent. This could lead to unauthorized access and control over sensitive data.

2. Heap Corruption: Exploitation of this vulnerability can result in heap corruption, which might affect the stability of the browser and potentially crash it, disrupting business operations and leading to lost productivity.

3. Data Breaches: If exploited successfully, this vulnerability could facilitate data breaches, where attackers gain access to confidential information stored within the browser or other integrated applications, resulting in financial loss and reputational damage for organizations.
