CVE-2026-113044: Type confusion in V8

Q: Who is exposed to this issue?

Users of Google Chrome versions earlier than 156.0.8078.47 are affected. Exploitation occurs through a crafted HTML page, so systems where users browse untrusted or attacker-controlled web content are exposed.

Q: What does an attacker need to exploit it?

The attacker needs to cause the target to load a crafted HTML page. The described impact is arbitrary code execution inside the browser sandbox; the provided information does not indicate that additional local access or authentication is required.

Q: How can I determine whether a system needs remediation?

Check the installed Google Chrome version. Versions prior to 156.0.8078.47 need to be updated.
