Impact

Type confusion in V8 in Google Chrome prior to 156.0.8078.47 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. The flaw is a type‑confusion memory‑management issue (CWE‑843) that can compromise the browser sandbox.

Affected Systems

Google Chrome users running a version earlier than 156.0.8078.47 are vulnerable. This includes any desktop Chrome installation that has not yet installed the latest stable update from Google’s release channel.

Risk and Exploitability

The CVSS score of 8.8 indicates high severity for this use‑after‑free. The attack vector is client‑side and requires the user to visit a malicious site that delivers a crafted HTML page. The EPSS score is less than 1%, indicating a very low exploitation probability, and the vulnerability is not listed in the CISA KEV catalog, so current exploit likelihood may be lower than a higher‑profile zero‑day. Nevertheless, the ability to execute code within the browser sandbox makes this a serious risk.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Install Chrome update 156.0.8078.47 or higher, or any newer release from Google’s stable channel.
  • Enable the built‑in Chrome sandbox if not already functioning, and ensure that all system processes related to Chrome are constrained by the operating system’s sandboxing mechanisms.
  • If upgrading is temporarily not possible, configure network filtering or content security policies that block loading of unsafe or untrusted HTML content, and consider disabling JavaScript for untrusted sites.
