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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Google Chrome's Loader component. It occurs when a program tries to use memory that has already been freed, potentially allowing a remote attacker to execute arbitrary code within a sandbox by tricking a user into visiting a specially crafted HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 151.0.7922.72. Detection involves checking the installed Chrome version. On Windows, run: wmic product where "name like 'Google Chrome'" get version. On Linux, run: google-chrome --version. If the version is below 151.0.7922.72, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your device. Since it occurs in Chrome's sandbox, the impact is limited to the browser's environment, but it could still lead to data theft, installation of malware, or unauthorized actions on websites you visit.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards as it is a technical flaw in Google Chrome's Loader component. However, if exploited, it could lead to arbitrary code execution which may result in unauthorized data access or processing, potentially violating GDPR or HIPAA requirements depending on the context of use.

Mitigation Strategies

Update Google Chrome to version 151.0.7922.72 or later to address the use after free vulnerability in the Loader component.
