Overview
CVE-2025-13229 is a high-severity vulnerability affecting Google Chrome versions prior to 142.0.7444.59. This vulnerability stems from a type confusion error within the V8 JavaScript engine. Successful exploitation of this flaw could allow a remote attacker to potentially trigger heap corruption through a specially crafted HTML page.
Technical Details
The root cause of CVE-2025-13229 lies in the way V8 handles certain data types during JavaScript execution. Due to incorrect type checking or validation, the engine can misinterpret the type of a variable or object. This type confusion can lead to memory corruption, specifically heap corruption, when V8 attempts to access or manipulate the data based on the incorrect type information.
The vulnerability is triggered when a user opens a malicious HTML page containing JavaScript code designed to exploit this type confusion. The attacker crafts the page to manipulate specific data structures within V8, leading to the exploitable condition.
CVSS Analysis
As indicated, a CVSS score and severity rating are currently N/A. However, the Chromium security team has assessed this as “High” severity. Given the potential for remote exploitation and heap corruption, a high CVSS score is anticipated in future analyses as more details become available.
Possible Impact
The exploitation of CVE-2025-13229 can have severe consequences:
- Arbitrary Code Execution: A successful exploit could allow an attacker to execute arbitrary code on the victim’s machine with the privileges of the Chrome process.
- Data Leakage: The attacker could potentially read sensitive data from the browser’s memory or the operating system.
- Denial of Service: The vulnerability could be exploited to crash the browser or even the entire system.
Mitigation or Patch Steps
The primary mitigation for CVE-2025-13229 is to update Google Chrome to version 142.0.7444.59 or later. Google has released a patch addressing this vulnerability in the specified version. Users are strongly advised to update their browsers immediately to protect themselves from potential attacks.
