AI Analysis

Impact

A flaw in Chrome’s WebAudio implementation permits an out‑of‑bounds read and write, allowing a remote attacker to corrupt the page’s heap. When the webpage is rendered, the corrupted heap can lead to arbitrary code execution, compromising the confidentiality, integrity, and availability of the user’s system. The weakness corresponds to CWE‑125 and CWE‑787.

Affected Systems

Google Chrome browsers prior to version 146.0.7680.153 are affected, regardless of operating system; the issue applies to Windows, macOS, and Linux deployments of the browser.

Risk and Exploitability

The CVSS score of 8.8 indicates a high severity risk. The EPSS score of less than 1% suggests a low likelihood of current exploitation, and it is not listed in CISA’s KEV catalog. The flaw can be triggered from a malicious webpage, implying a remote web‑based attack vector where an attacker hosts a crafted HTML page to exploit the WebAudio bug and achieve code execution.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update Google Chrome to version 146.0.7680.153 or newer.
  • Verify that the browser reports the updated version number.
  • If an immediate update is not possible, temporarily block WebAudio usage by disabling audio in the browser settings or applying a content security policy that restricts media playback.
