AI Analysis

Impact

This vulnerability is caused by an inappropriate implementation in the Chromoting component of Google Chrome on Linux. A malicious user who can send crafted network traffic to a Chrome instance may cause the browser to execute code with elevated privileges. As a result, the attacker can gain operating‑system level access, potentially enabling full control of the affected machine. The weakness is reflected in the CWE identifiers for improper authorization and insecure communication handling.

Affected Systems

Google Chrome on Linux systems running versions prior to 151.0.7922.72 is affected. The issue specifically targets the Chromoting feature, which is used to support remote desktop functionality.

Risk and Exploitability

The CVSS score of 8.4 qualifies the vulnerability as high severity. The EPSS score of less than 1% indicates a very low current exploitation probability, and the vulnerability is not listed in CISA’s KEV catalog. Based on the description, the likely attack vector is a local attacker using malicious network traffic to interact with the Chromoting service. Exploitation requires that the Chrome instance be running on the victim machine with the vulnerable version, and no additional user interaction is required beyond initiating the traffic. The impact is an elevation of privileges to full OS control.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Google Chrome to version 151.0.7922.72 or newer to receive the fix for the Chromoting implementation issue.
  • Disable or uninstall the Chromoting remote‑desktop functionality through Chrome policies or the browser’s settings to eliminate the vulnerable component.
  • Configure local firewall rules to block traffic to the ports used by Chromoting on the victim machine, preventing malicious network interaction.
