Overview
CVE-2025-13227 is a high-severity security vulnerability affecting Google Chrome’s V8 JavaScript engine. Specifically, a type confusion flaw exists in versions prior to 142.0.7444.59. This vulnerability could allow a remote attacker to potentially exploit heap corruption by enticing a user to open a specially crafted HTML page. Google has classified this as a “High” severity issue (Chromium security severity: High), necessitating immediate patching.
Technical Details
The core of CVE-2025-13227 lies in a type confusion issue within the V8 JavaScript engine. Type confusion occurs when the engine incorrectly infers the type of a variable, leading to unexpected behavior. In this specific case, the incorrect type handling can be leveraged by a malicious actor to corrupt the heap memory. By crafting a malicious HTML page, an attacker can trigger this type confusion and potentially gain control over the browser’s execution, leading to arbitrary code execution.
