Exploitability

CWE

KEV

CWE ID	Description
CWE-367	The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Executive Summary

This vulnerability is a use-after-free issue in WebProtect within Google Chrome. It occurs when a program tries to use memory that has already been freed, potentially allowing a remote attacker to execute arbitrary code inside the browser's sandbox. The attacker would need to trick a user into visiting a specially crafted HTML page.

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 terminal. If the version is below 156.0.8078.47, the system is vulnerable. Update Chrome to the latest version to mitigate the risk.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your device.

Users should update Chrome to the latest version to mitigate this risk.

Compliance Impact

This vulnerability could potentially lead to unauthorized code execution, which may result in data breaches or unauthorized access to sensitive information. Such incidents could violate GDPR's data protection requirements or HIPAA's safeguards for protected health information if exploited.
