CVE-2024-7974Network attack vector

Heap corruption via malformed V8 API input

Published Aug 21, 2024 · Updated Mar 19, 2025

Insufficient data validation in Google Chrome's V8 API before 128.0.6613.84 allows remote attackers to corrupt heap memory via a crafted extension. The public record identifies only the V8 API and does not disclose which entry point accepts invalid extension-controlled data or which validation is missing. Reaching the flaw requires a crafted Chrome extension to invoke that API, and published sources establish no consequence beyond heap corruption.
