Use After Free Vulnerability in Google Chrome Web Browser

CVE-2025-3066

What is CVE-2025-3066?

CVE-2025-3066 is a high-severity vulnerability affecting the Google Chrome web browser, specifically versions prior to 135.0.7049.52. This flaw arises due to a use-after-free condition in the browser's navigation feature, which can lead to heap corruption. If exploited, this vulnerability poses a significant risk to organizations as it could potentially allow attackers to execute arbitrary code via specially crafted HTML pages, compromising user security and system integrity.

Technical Details

The vulnerability is categorized as a use-after-free issue, which occurs when a program continues to reference memory that has already been released. In this specific scenario, the flaw is tied to the navigation processes within Google Chrome. The affected versions do not manage memory correctly, leading to the possibility of an attacker crafting web content that can manipulate browser memory. This manipulation could ultimately facilitate malicious actions on affected systems.

Potential Impact of CVE-2025-3066

1. Remote Code Execution: The primary threat posed by CVE-2025-3066 is the potential for remote code execution. Attackers could exploit this vulnerability to run arbitrary code on a victim's machine, leading to unauthorized access and control.

2. Heap Corruption: The use-after-free vulnerability can lead to heap corruption, which may destabilize the browser and result in crashes, data loss, or further vulnerabilities being exploited by malicious actors.

3. Data Breaches: Organizations using vulnerable versions of Google Chrome risk exposure of sensitive data as attackers leveraging this vulnerability could access user information, personal data, or corporate documents, leading to significant privacy and security violations.
