Overview
The security vulnerability under focus, CVE-2025-10501, is a high-severity flaw affecting Google Chrome’s WebRTC component. This flaw is of particular concern to both individuals and organizations due to the vast number of users who depend on Google Chrome for their browsing needs. The vulnerability is a ‘use after free’ type, which allows a remote attacker to potentially exploit heap corruption through a specially crafted HTML page, leading to a significant threat to system integrity and confidentiality of data.

How the Exploit Works
The exploit hinges on the ‘use after free’ vulnerability within the WebRTC component of Google Chrome. In a ‘use after free’ scenario, a program continues to use memory after it has been freed or de-allocated. In this specific instance, a remote attacker crafts a malicious HTML page that, when loaded and interacted with by the victim, triggers the vulnerability, leading to heap corruption. The attacker can then leverage this corruption to perform arbitrary code execution or even take control of the system.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited. It is a simple HTML page with embedded JavaScript code that triggers the ‘use after free’ flaw in the WebRTC component.
<html>
<body>
<script>
// Initialize WebRTC connection
var rtcConn = new RTCPeerConnection();
// Trigger 'use after free' vulnerability
var maliciousPayload = "...";
// Leverage heap corruption
// Details of this part are intentionally omitted
rtcConn.createOffer().then((desc) => {
rtcConn.setLocalDescription(desc);
});
</script>
</body>
</html>In this example, the `maliciousPayload` would be replaced with the actual malicious code that exploits the heap corruption. As this is a conceptual example, the specifics of that payload are intentionally omitted.
