Technical details

A use-after-free (UAF) vulnerability exists in the CSS component of the Chromium browser engine. The flaw is triggered when the browser incorrectly manages memory while processing Cascading Style Sheets (CSS) on a web page. A remote, unauthenticated attacker can exploit this by hosting a specially crafted HTML page; when a user visits this page, the attacker can cause heap corruption. This can lead to arbitrary code execution within the browser's sandbox environment. The vulnerability is confirmed to be exploited in the wild and is patched in Chrome version 145.0.7632.75 and later.
