Exploitability

CWE

KEV

CWE ID	Description
CWE-862	The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Extensions component. It occurs when a program tries to use memory that has already been freed, potentially leading to arbitrary code execution within the browser's sandbox. An attacker could exploit this by crafting a malicious HTML page that triggers the flaw.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 156.0.8078.47. 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 156.0.8078.47, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow a remote attacker to run arbitrary code on your system through a specially designed webpage. Since it affects Chrome's sandbox, the attacker would have limited access but could still compromise your browser session or steal sensitive data.

Compliance Impact

This vulnerability is a use-after-free issue in Google Chrome's Extensions component, which could allow a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. While the vulnerability itself does not directly impact compliance with standards like GDPR or HIPAA, it could potentially lead to unauthorized data access or code execution, which may violate data protection requirements under these regulations if exploited.

Mitigation Strategies

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