Exploitability

CWE

KEV

CWE ID	Description
CWE-863	The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 vulnerability is a use-after-free issue in Google Chrome's Media component on Windows systems. It occurs when a program tries to use memory that has already been freed, potentially allowing a remote attacker to execute arbitrary code within the sandbox by tricking a user into visiting a specially crafted HTML page.

Detection Guidance

Detection of this vulnerability requires checking the installed version of Google Chrome. If your version is prior to 156.0.8078.47, the system is vulnerable. Use commands like 'google-chrome --version' or check via package manager (e.g., 'apt list --installed | grep chrome' on Debian/Ubuntu).

No direct detection commands are provided for the use-after-free flaw itself, as it requires code execution to trigger. Focus on version verification and applying updates.

Impact Analysis

An attacker could exploit this to run malicious code on your computer, potentially stealing data, installing malware, or taking control of your system. Since it affects Chrome, simply visiting a compromised website could trigger the exploit.

Compliance Impact

This vulnerability allows remote code execution inside the sandbox via a crafted HTML page, which could lead to unauthorized data access or manipulation. Such risks may impact compliance with GDPR (data protection) and HIPAA (health data privacy) by potentially exposing sensitive user or patient information.

Mitigation Strategies

Update Google Chrome to version 156.0.8078.47 or later to address the use-after-free vulnerability in Media.
