Impact

A use‑after‑free vulnerability in the AdFilter component of Google Chrome allows attackers to execute arbitrary code outside the browser sandbox via a crafted HTML page. The flaw is triggered when malicious content is rendered, causing the browser to access freed memory and run malicious instructions. This results in full system compromise, with the attacker acquiring the same privileges as the user running Chrome.

Affected Systems

The flaw affects all installations of Google Chrome before version 154.0.8037.57. Users running 154.0.8037.56 or older are vulnerable. Updating to 154.0.8037.57 or later removes the bug.

Risk and Exploitability

The vulnerability carries a CVSS score of 9.6, indicating critical severity. It has an EPSS score of 0.00409, meaning the probability of exploitation is very low but not zero. The flaw is not listed in the CISA KEV catalog. The attack is remotely exploitible over the internet by delivering a malicious HTML page to a victim's browser.
