Doc Text:
A flaw was found in Google Chrome on Android. This vulnerability, located in the Shared Tab Groups component, is a 'use after free' issue, which means the software attempts to use memory after it has been freed, potentially leading to corruption. A remote attacker could exploit this by leveraging social engineering and a specially crafted HTML page to execute arbitrary code outside of the browser's security sandbox. This could result in a complete compromise of the affected system.
