A critical use after free vulnerability in Google Chrome for Windows could allow a remote attacker to execute arbitrary code by leveraging a compromised renderer process.

The flaw is a use after free vulnerability (CWE-416) within the Chromoting component, which can be triggered by an unauthenticated remote attacker who has already compromised the browser renderer process.

The vulnerability poses a severe risk to organizational security, as successful exploitation enables remote code execution outside the browser sandbox. With a CVSS score of 8.3, this high severity flaw could lead to full system compromise, unauthorized data access, and the potential for lateral movement within the network.

Immediate Action: Update all instances of Google Chrome on Windows to version 152.0.7977.65 or later immediately.

Proactive Monitoring: Review endpoint security logs for anomalous network traffic patterns associated with the browser process and monitor for unexpected child process execution.

Compensating Controls: Ensure that browser-based sandboxing features are fully enabled and utilize endpoint detection and response (EDR) solutions to identify and block suspicious shell executions originating from browser processes.

Public Exploit Available: No

Given the high CVSS score and the potential for remote code execution, this vulnerability represents a significant threat to browser security. IT administrators should prioritize the deployment of the latest Chrome version across all Windows assets to close this security gap and protect against potential exploitation.
