# Type confusion in V8 in Google Chrome prior to 128.0.6613.84 allowed a remote attacker to exploit heap corruption…

Chromium's V8 JavaScript engine has a type confusion bug that corrupts heap memory when a victim loads a crafted HTML page. An attacker who lures a user to that page can potentially run code in the browser.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Google Chromium V8 affected ? fixed ?

- vendor:microsoft edge affected < 128.0.2739.42 fixed 128.0.2739.42

## How to check

Check the installed browser version (for Chrome: chrome://settings/help; for Edge and Opera, their About pages) and compare it with the fixed release named in the vendor advisory.

## Fix

Update Google Chrome, Microsoft Edge, Opera and any other Chromium-based browser to a release that includes the V8 fix for CVE-2024-7971.
