Deeper analysisAI
CVE-2025-2135 is a type confusion vulnerability (CWE-843) in the V8 JavaScript engine within Google Chrome versions prior to 134.0.6998.88. It enables a remote attacker to potentially trigger heap corruption by processing a crafted HTML page. The Chromium security team classifies it as High severity, with 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).
A remote attacker without privileges can exploit this vulnerability over the network with low complexity by luring a user to interact with a malicious site, such as visiting a webpage or opening an HTML document. User interaction is required, but successful exploitation could result in high confidentiality, integrity, and availability impacts, including heap corruption that may lead to code execution or system compromise.
