# Type Confusion in V8 in Google Chrome prior to 116.0.5845.179 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 user to open a crafted HTML page. It is listed as actively exploited in the wild and affects Chromium-based browsers such as Chrome, Edge and Opera.

_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 < 116.0.5845.179 fixed 116.0.5845.179
- vendor:debian linux affected = 11.0 fixed ?
- vendor:debian linux affected = 12.0 fixed ?
- vendor:fedoraproject fedora affected = 37 fixed ?
- vendor:fedoraproject fedora affected = 38 fixed ?
- vendor:fedoraproject fedora affected = 39 fixed ?
- vendor:microsoft edge chromium affected < 116.0.1938.76 fixed 116.0.1938.76

## How to check

Open the browser's version page (chrome://version or edge://version) and compare the version against the vendor's fixed release.

## Fix

Update the browser to the patched Chromium release from the vendor; the exact fixed version is not in the sources.
Discontinue use of the affected browser if no update is available, as CISA requires.

## 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.
