CVE-2026-103625: Type confusion in V8

Q: Who is exposed to this vulnerability?

Users of Google Chrome versions earlier than 154.0.8037.97 are affected. Exploitation occurs through a crafted HTML page, so users who browse attacker-controlled or compromised web content are exposed.

Q: What does an attacker need to exploit it?

The CVSS vector indicates network-based exploitation with low attack complexity and no privileges required. User interaction is required, consistent with a victim loading a crafted HTML page.

Q: Does successful exploitation escape the browser sandbox?

No. The issue allows arbitrary code execution inside the sandbox; the provided information does not indicate a sandbox escape.

Q: What should be updated?

Update Google Chrome to version 154.0.8037.97 or later. The vulnerability affects versions prior to that release.
