Overview
CVE-2025-6192 is a severe vulnerability in Google Chrome that could potentially allow an attacker to exploit heap corruption via a carefully crafted HTML page. This vulnerability is of high significance due to the widespread usage of Google Chrome as a default browser across multiple platforms, making a large number of users potentially susceptible to system compromise or data leakage. The severity of this issue is further emphasized by its high CVSS severity score of 8.8, indicating a significant impact if exploited.

How the Exploit Works
The exploit takes advantage of a “use after free” vulnerability in Metrics in Google Chrome. In essence, this means that the software continues to use a pointer after it has been freed. This can lead to two types of vulnerabilities: the software could potentially read old data or it might write data into the wrong location. In this particular exploit, a remote attacker can craft an HTML page that triggers this vulnerability, leading to heap corruption. The attacker can then use this corruption to execute arbitrary code, potentially leading to system compromise or data leakage.
Conceptual Example Code
A conceptual example of how this vulnerability might be exploited could be a malicious HTML page that triggers the use-after-free condition. This example is not real code, but is meant to illustrate the concept:
<!DOCTYPE html>
<html>
<body>
<script>
// Code that triggers the use-after-free condition in Metrics
triggerUseAfterFree();
// Code that takes advantage of the heap corruption to execute arbitrary commands
exploitHeapCorruption();
</script>
</body>
</html>This code would need to be hosted on a webpage and the victim would need to visit this page for the exploit to be successful. It is crucial to regularly update your browser and other software to protect yourself from such vulnerabilities.
