Deeper analysis
The vulnerability is a use-after-free flaw in the Navigation component of Google Chrome versions prior to 119.0.6045.159. It is tracked as CWE-416 and rated high severity by Chromium, with a CVSS 3.1 score of 8.8 reflecting network attack vector, low complexity, and no required privileges.
A remote attacker can exploit the issue by serving a specially crafted HTML page to a victim, triggering heap corruption that may allow arbitrary code execution within the browser process after the user interacts with the page.
The official Chrome stable channel update and corresponding Fedora package advisories state that the issue is resolved by upgrading to version 119.0.6045.159 or later. A proof-of-concept targeting the NavigationURLLoaderImpl fallback path has been published, but the EPSS score has remained flat at its peak value of 0.2819.
