CVE-2025-0445

What is CVE-2025-0445?

CVE-2025-0445 is a high-severity vulnerability identified in Google Chrome, specifically affecting the V8 JavaScript engine prior to version 133.0.6943.53. This vulnerability stems from a "use after free" condition, where memory that has already been released (or freed) is still being accessed, leading to potential heap corruption. This flaw can be exploited through specially crafted HTML pages, allowing remote attackers to execute arbitrary code. Given the widespread use of Google Chrome for web browsing within organizations, an exploitation of this vulnerability could enable attackers to take control of a victim's browser environment, posing a significant security risk.

The implications of this vulnerability can extend beyond mere browser performance issues; successful exploitation could lead to unauthorized data access, installation of malicious payloads, or other malicious actions that compromise organizational assets and personal information.

Potential impact of CVE-2025-0445

1. Remote Code Execution: The vulnerability allows attackers to execute arbitrary code on users' machines, which can lead to full system compromise and unauthorized access to sensitive data.

2. Data Breaches: By exploiting this vulnerability, attackers may gain access to confidential information stored within the browser, putting organizational and personal data at dire risk of theft or manipulation.

3. Widespread Threat: Given that Google Chrome has a significant user base, the potential exploitation of this vulnerability could affect numerous organizations, increasing the scale of impact and creating a fertile ground for further attacks or exploitation by cybercriminal groups.
