AI Analysis

Impact

The vulnerability is a use‑after‑free bug in the Document Object Model (DOM) handling of Google Chrome prior to version 155.0.8059.79. This flaw allows a remote attacker to execute arbitrary code inside the browser sandbox by delivering a specially crafted HTML page. The weakness is identified as CWE‑416 and can compromise confidentiality, integrity, and availability of the user session.

Affected Systems

Google’s Chrome browser, versions earlier than 155.0.8059.79, are affected. Users of the stable desktop channel before that update are vulnerable.

Risk and Exploitability

The CVSS score of 8.8 classifies the flaw as high severity, but the EPSS score of less than 1 percent indicates a low probability of widespread exploitation at the time of this analysis. The vulnerability is not listed in CISA’s KEV catalog. Based on the description, the likely attack vector is a malicious web page that the user visits or otherwise loads into Chrome. An attacker can craft an HTML file or URL that triggers the use‑after‑free, resulting in arbitrary code execution inside the sandboxed browser context.
