AI Analysis

Impact

The vulnerability is a use‑after‑free in the Scroll component of Google Chrome before build 156.0.8078.47. An attacker can serve a crafted HTML page that may cause Chrome to execute arbitrary code inside the browser sandbox. The flaw is classified as CWE-416. The attack could let the attacker run code with sandbox privileges, affecting only the browsing session while the user remains logged into their account.

Affected Systems

Google Chrome versions earlier than 156.0.8078.47 are vulnerable. (The specific platforms are not stated in the CVE.) The flaw is identified in the Chrome browser release and affects all users running the affected builds.

Risk and Exploitability

The CVSS score of 8.8 indicates a high potential for exploitation, but the EPSS score of < 1% suggests that attacks are unlikely at present. The vulnerability is not listed in CISA’s KEV catalog. Exploitation requires the victim to load a crafted HTML page. The attack vector is a remote web content attack; theories that it might be delivered via email or a malicious website are inferred from common delivery methods but are not explicitly stated in the CVE.
