AI Analysis

Impact

A memory corruption in the Paint component of Google Chrome is triggered by a crafted HTML page, enabling remote code execution by allowing the attacker to run arbitrary code in the browser context. The vulnerability was rated as High by Chromium security and classified as CWE‑200. While it can expose cross‑origin data, its primary impact is the ability to execute arbitrary code.

Affected Systems

Google Chrome versions prior to 156.0.8078.47 on any platform that includes the Paint component are vulnerable. The issue affects the rendering engine across supported operating systems, and any client running a vulnerable release.

Risk and Exploitability

The CVSS score of 8.8 classifies the flaw as high severity. An EPSS score of <1% indicates a very low predicted exploitation probability. The vulnerability is not listed in the CISA KEV catalog. This memory corruption can lead to remote code execution. Based on the description, the likely attack vector is a specially crafted HTML page that triggers the memory corruption while a user browses. Updating to Chrome 156.0.8078.47 or newer mitigates the issue.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update Google Chrome to version 156.0.8078.47 or newer to apply the memory corruption fix.
  • If an update cannot be applied immediately, limit user access to potentially malicious HTML pages or disable the Paint component via enterprise policy until the vulnerability is patched.
  • Strengthen browser security configuration to restrict the execution of untrusted content, such as enabling the built‑in sandbox features or applying a policy that blocks risky HTML elements.
