Impact

A use‑after‑free flaw in Google Chrome prior to 155.0.8059.39 allows a remote attacker, via a crafted HTML page, to execute arbitrary code outside the browser sandbox. The vulnerability is a critical severity issue and is mapped to CWE-416, identifying a scenario where freed memory is accessed after deallocation.

Affected Systems

Google Chrome browsers older than 155.0.8059.39 on all supported platforms are vulnerable. The affected versions include every release before the 155.0.8059.39 patch, regardless of operating system, due to the shared use‑after‑free path in the browser engine.

Risk and Exploitability

EPSS data is not available, but the CVSS score of 9.6 is classified as Critical, and the vulnerability is listed in Google’s Chromium security advisories. The likely attack vector is through a malicious web page or script page that a victim visits, enabling an attacker to run code with local privileges outside the browser sandbox. Because the flaw permits execution beyond the browser’s security boundaries, it presents a high risk to user data, system integrity, and confidentiality.
