AI Analysis

Impact

The vulnerability is a type confusion bug in the V8 JavaScript engine used by Google Chrome. It allows a remote attacker to read memory inside the sandbox through a specially crafted HTML page. This could expose the contents of the sandbox and potentially enable further exploitation of privileges within the browser process.

Affected Systems

Google Chrome on all platforms, for all releases earlier than version 153.0.8010.36.

Risk and Exploitability

Chromium classifies this flaw as high severity with a CVSS score of 4.3. The EPSS score is < 1%, and it is not listed in the CISA KEV catalog. The exploit requires delivery of a malicious web page that triggers V8's type confusion, meaning an attacker could target users by hosting a malicious site or injecting the payload into compromised content. As the vulnerability permits reading of sandbox memory, it offers an opportunity for attackers to gather sensitive data and potentially pivot to additional attacks.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update Chrome to version 153.0.8010.36 or later to apply the V8 patch.
  • Ensure that Chrome’s sandboxing feature is enabled in the browser’s security settings.
  • If an immediate update is not possible, mitigate by blocking malicious scripts with content‑security policies or browser extensions that prevent execution of untrusted JavaScript.
