A type confusion bug in the V8 JavaScript engine used by Chromium lets a remote attacker corrupt heap memory by getting a victim to load a crafted HTML page. The sources say it is exploited in the wild, and heap corruption in a browser engine is typically used to run attacker code in the browser.

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