# Chrome: media use-after-free lets a crafted page run code in sandbox

A use-after-free bug in Chrome's Media component lets a remote attacker run arbitrary code inside the browser sandbox when a victim opens a crafted HTML page. The sandbox limits what that code can do on the machine, but it is still code execution from a web page.

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

## Fix

Update Google Chrome to 156.0.8078.47 or later and restart the browser.
