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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 DOM 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 the browser's sandbox by tricking a user into visiting a specially crafted HTML page.

This vulnerability is specific to Google Chrome versions prior to 151.0.7922.173. To detect it, check your Chrome version by running chrome --version or chrome://settings/help in the browser. If your version is below 151.0.7922.173, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your computer through your web browser. This could lead to unauthorized access to your data, installation of malware, or other harmful actions while you are browsing the internet.

Compliance Impact

This vulnerability is a use-after-free issue in Google Chrome's DOM, which could allow remote attackers to execute arbitrary code. Such vulnerabilities may lead to unauthorized data access or manipulation, potentially violating GDPR's integrity and confidentiality requirements or HIPAA's safeguards for protected health information. However, specific compliance impacts depend on implementation and mitigation measures.

Mitigation Strategies

Update Google Chrome to version 151.0.7922.173 or later to address the use-after-free vulnerability in the DOM component.
