# Chrome: use-after-free in Passwords lets a web page run code

A memory bug in the Passwords component of Google Chrome, before version 157.0.8103.38, lets a crafted HTML page trigger a use-after-free. Per the description, an attacker could potentially execute arbitrary code outside the browser sandbox.
