# V8 in Google Chrome prior to 54.0.2840.90 for Linux, and 54.0.2840.85 for Android, and 54.0.2840.87 for Windows and…

A flaw in the V8 JavaScript engine inside Chromium lets a crafted HTML page read and write memory out of bounds. An attacker can use this to run code when a victim opens the page in an affected browser.

_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 < 54.0.2840.90 fixed 54.0.2840.90
- vendor:google chrome affected < 54.0.2840.85 fixed 54.0.2840.85
- vendor:google chrome affected < 54.0.2840.87 fixed 54.0.2840.87
- vendor:redhat enterprise linux desktop affected = 6.0 fixed ?
- vendor:redhat enterprise linux server affected = 6.0 fixed ?
- vendor:redhat enterprise linux workstation affected = 6.0 fixed ?

## How to check

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

## Fix

Update Google Chrome, Microsoft Edge, Opera or other Chromium-based browsers to a release that includes the vendor fix.

## From the sources

Google Chromium V8 Engine contains an out-of-bounds memory access vulnerability that allows a remote attacker to perform read/write operations, leading to code execution, 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 updates per vendor instructions.
