Executive Summary

This is a heap buffer overflow vulnerability in WebRTC within Google Chrome versions before 151.0.7922.72. A heap buffer overflow occurs when a program writes more data to a memory buffer than it can hold, potentially corrupting adjacent memory. In this case, a remote attacker could exploit this by tricking a user into visiting a specially crafted HTML page, leading to an out-of-bounds memory read.

Impact Analysis

The impact includes potential crashes of the Chrome browser, exposure of sensitive memory data, or even arbitrary code execution if combined with other exploits. However, the severity is rated as Low by Chromium, suggesting limited practical risk under normal conditions.

Mitigation Strategies

Update Google Chrome to version 151.0.7922.72 or later to address the heap buffer overflow in WebRTC.
