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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 the Accessibility component of Google Chrome versions before 156.0.8078.47. A use-after-free occurs when a program continues to use a pointer after the memory it points to has been freed, potentially leading to arbitrary code execution.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 156.0.8078.47. To detect it, check your Chrome version by running chrome://version/ in the browser. If your version is below 156.0.8078.47, update Chrome immediately. No direct network detection commands are provided for this use-after-free issue.

Impact Analysis

An attacker could exploit this by tricking a user into visiting a specially crafted HTML page, which may allow them to execute arbitrary code within the browser's sandbox. This could lead to unauthorized access to sensitive data or control of the affected system.

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 Accessibility feature. However, if exploited, it could lead to unauthorized code execution, potentially compromising user data and violating privacy requirements under GDPR or HIPAA depending on the context of use.

Mitigation Strategies

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