vulnerability analysis and mitigation
Overview
A high-severity use-after-free vulnerability (CVE-2025-0445) was discovered in Google Chrome's V8 JavaScript engine. The vulnerability affects Chrome versions prior to 133.0.6943.53 and was reported by an anonymous researcher identified as '303f06e3' on January 27, 2025. The flaw allows remote attackers to potentially exploit heap corruption through a specially crafted HTML page (Chrome Releases, Security Online).
Technical details
The vulnerability is classified as a use-after-free (CWE-416) issue in Chrome's V8 JavaScript engine. According to the CVSS 3.1 scoring system, it received a base score of 5.4 (Medium) with the following vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N. This indicates that the vulnerability can be exploited remotely, requires low attack complexity, needs no privileges, but does require user interaction (NVD, Palo Alto).
Impact
The vulnerability could potentially lead to heap corruption if successfully exploited through a crafted HTML page. Given its presence in the V8 JavaScript engine, which is crucial for processing JavaScript code, the vulnerability could have significant security implications. The CVSS scoring indicates potential impacts on both confidentiality and integrity, though with limited scope (Security Online).
