Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This is a use-after-free vulnerability in WebRTC within Google Chrome versions before 152.0.7977.65. A use-after-free occurs when a program continues to use memory after it has been freed, potentially leading to arbitrary code execution. In this case, a remote attacker could exploit this by crafting a malicious HTML page to trigger the flaw.

Impact Analysis

If exploited, this vulnerability could allow an attacker to execute arbitrary code on your system, potentially taking control of your device. Since it affects Chrome's sandbox, the attacker might bypass security restrictions to run malicious code inside the sandbox environment.

Mitigation Strategies

Update Google Chrome to version 152.0.7977.65 or later to address the use after free vulnerability in WebRTC.
