Overview
CVE-2025-13224 is a high-severity vulnerability affecting Google Chrome’s V8 JavaScript engine. This vulnerability, identified as a type confusion issue, could allow a remote attacker to potentially exploit heap corruption through a specially crafted HTML page. The vulnerability was patched in Chrome version 142.0.7444.175.
Technical Details
The vulnerability stems from a type confusion error within the V8 JavaScript engine. This occurs when the engine incorrectly infers the type of an object, leading to incorrect memory access and potential heap corruption. An attacker can leverage this by crafting a malicious HTML page that triggers the type confusion error during JavaScript execution. Successful exploitation could lead to arbitrary code execution within the context of the Chrome browser process.
While specific details of the exploit are not publicly available (likely to prevent further exploitation), the Chromium security team has classified this as a High severity issue, indicating the potential for significant impact.

Currently, a CVSS score is not available for CVE-2025-13224. However, based on the Chromium security severity rating of “High,” it can be inferred that the vulnerability presents a significant risk. A full CVSS score will provide more specific details about the exploitability and impact of the vulnerability, including metrics for attack vector, attack complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact. Once a CVSS score is published, this section will be updated.
Possible Impact
Successful exploitation of CVE-2025-13224 could have serious consequences:
- Arbitrary Code Execution: An attacker could potentially execute arbitrary code on the victim’s machine within the context of the Chrome browser.
- Data Theft: Sensitive data, such as cookies, session tokens, and stored passwords, could be stolen.
- System Compromise: In some scenarios, the attacker could potentially escalate privileges and gain control of the entire system.
- Denial of Service: The vulnerability could be exploited to crash the browser, leading to a denial of service.
Mitigation/Patch Steps
The vulnerability has been addressed in Google Chrome version 142.0.7444.175. Users are strongly advised to update to this version or later immediately. Automatic updates are typically enabled in Chrome, but users can manually check for updates by:
- Opening Google Chrome.
- Clicking on the three dots (menu) in the top right corner.
