Deeper analysisAI
A type confusion vulnerability, designated CVE-2025-13227, affects the V8 JavaScript engine in Google Chrome prior to version 142.0.7444.59. Published on 2025-11-18, it enables a remote attacker to potentially trigger heap corruption via a crafted HTML page. The issue carries a Chromium security severity of High and a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), classified under CWE-843.
Exploitation requires no privileges and can be initiated remotely over the network with low complexity, though it depends on user interaction, such as visiting a malicious site. An attacker could achieve heap corruption, leading to high-impact confidentiality, integrity, and availability violations, potentially allowing arbitrary code execution within the renderer process.
Chrome's stable channel update, documented at https://chromereleases.googleblog.com/2025/10/stable-channel-update-for-desktop_28.html, patches this by advancing to version 142.0.7444.59.
