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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 V8, the JavaScript engine used by Google Chrome. It occurs when a program tries to use memory that has already been freed, potentially leading to arbitrary code execution. An attacker could exploit this by crafting a malicious HTML page to trigger the flaw, allowing them to run code within Chrome's sandboxed environment.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 153.0.8010.36. Detection involves checking the installed Chrome version. On Windows, run: wmic product where name='Google Chrome' get version. On Linux, run: google-chrome --version. If the version is below 153.0.8010.36, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to execute arbitrary code on your system through a malicious webpage. This could lead to unauthorized access, data theft, or installation of malware. Since it affects Chrome's sandbox, the impact is limited but still serious as it bypasses normal security boundaries.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code inside the sandbox via crafted HTML pages, which could lead to unauthorized data access or manipulation. This may impact compliance with GDPR by risking personal data breaches and HIPAA by potentially exposing protected health information if exploited in healthcare environments.

Mitigation Strategies

Update Google Chrome to version 153.0.8010.36 or later to address the use after free vulnerability in V8.
