Doc Text:
A flaw was found in Google Chrome. A remote attacker, who has already compromised the browser's renderer process, could exploit a use-after-free vulnerability. This can be achieved by enticing a user to visit a specially crafted HTML page. Successful exploitation could allow the attacker to perform a sandbox escape, potentially gaining elevated privileges or further access to the underlying system.
