# Type Confusion in V8 in Google Chrome prior to 125.0.6422.112 allowed a remote attacker to execute arbitrary code…

A type confusion bug in Chromium's V8 JavaScript engine lets a remote attacker run code by getting a victim to load a crafted HTML page. It is listed as actively exploited in the wild by CISA.

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

## Affected

- vendor:Google Chromium V8 affected ? fixed ?
- vendor:google chrome affected < 125.0.6422.112 fixed 125.0.6422.112
- vendor:fedoraproject fedora affected = 39 fixed ?
- vendor:fedoraproject fedora affected = 40 fixed ?

## How to check

Check the browser version: in Chrome or Edge open the about page (chrome://settings/help or edge://settings/help) and compare against the fixed release, which the sources do not name.

## Fix

Update Google Chrome, Microsoft Edge, Opera and other Chromium browsers to the vendor's patched release; the exact fixed version is unknown from these sources.
CISA says to apply vendor mitigations or stop using the product if none exist.

## From the sources

Google Chromium V8 contains a type confusion vulnerability that allows a remote attacker to execute code via a crafted HTML page. This vulnerability could affect multiple web browsers that utilize Chromium, including, but not limited to, Google Chrome, Microsoft Edge, and Opera.

CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
