A high-severity use after free vulnerability in Google Chrome Extensions poses a significant risk of heap corruption and potential code execution if a user installs a malicious extension.

This vulnerability is a use after free (CWE-416) flaw located within the Extensions component of the browser. It requires user interaction, specifically convincing a victim to install a malicious extension, after which a crafted HTML page can trigger heap corruption.

The exploitation of this vulnerability could lead to arbitrary code execution, resulting in full system compromise or sensitive data theft from the browser environment. Given the high CVSS score of 8.8, this flaw represents a critical threat to organizational security, particularly for users who frequently install browser extensions.

Immediate Action: Update Google Chrome to version 146.0.7680.71 or later to apply the necessary security patches.

Proactive Monitoring: Monitor endpoint logs for suspicious extension installation patterns or unusual browser process activity that may indicate heap manipulation attempts.

Compensating Controls: Implement browser management policies to restrict the installation of extensions to only those explicitly approved or managed by the organization.

Public Exploit Available: Unknown

This vulnerability presents a severe risk due to the potential for heap corruption within the browser engine. Security teams must prioritize updating all instances of Google Chrome across the organization to version 146.0.7680.71 immediately to mitigate the risk of remote exploitation.
