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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 vulnerability is a use-after-free issue in V8, the JavaScript engine used by Google Chrome. A use-after-free occurs when a program continues to use a pointer to memory that has already 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 and execute code within Chrome's sandbox.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 151.0.7922.72. To detect it, check your Chrome version by running chrome://version/ in the browser address bar. If your version is below 151.0.7922.72, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run arbitrary code on your system through a malicious webpage. Since it occurs within Chrome's sandbox, the impact is limited to the browser's environment. However, 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 other standards as it is a technical flaw in Google Chrome's V8 engine. However, if exploited, it could lead to arbitrary code execution, potentially compromising data confidentiality and integrity, which may impact compliance obligations under regulations like GDPR or HIPAA.

Mitigation Strategies

Update Google Chrome to version 151.0.7922.72 or later to address the use after free vulnerability in V8.
