A critical heap buffer overflow in Google Chrome’s WebRTC implementation presents a substantial risk of remote code execution.

This vulnerability is a heap buffer overflow within the WebRTC subsystem, which handles real-time communication. An unauthenticated attacker can trigger this overflow by sending specially crafted packets, potentially leading to arbitrary code execution.

With a CVSS score of 8.8, this vulnerability is highly dangerous as it affects the WebRTC stack, which is frequently used for modern communication tools. Successful exploitation could lead to total system compromise, bypassing standard browser security boundaries.

Immediate Action: Update all instances of Google Chrome to version 149 or higher immediately.

Proactive Monitoring: Monitor for unexpected network traffic or spikes in WebRTC-related service usage that may indicate exploitation.

Compensating Controls: Use a network-level firewall or Web Application Firewall to inspect and filter suspicious traffic patterns associated with WebRTC.

Public Exploit Available: false

Heap buffer overflows are classic vectors for remote code execution. Given the ubiquity of WebRTC, it is imperative that all browser instances are updated to version 149 immediately to close this critical security gap.
