Exploitability

CWE

KEV

CWE ID	Description
CWE-345	The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Google Chrome before version 156.0.8078.47. It occurs when a program tries to use memory that has already been freed, potentially allowing a remote attacker to execute arbitrary code within the browser's sandbox by tricking 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 browser address bar. If your version is below 156.0.8078.47, the system is vulnerable. Update Chrome immediately 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 through a compromised webpage. Since it occurs in the sandbox, the impact is limited to the browser's environment, but it could still lead to data theft, installation of malware, or unauthorized actions on websites you visit.

Compliance Impact

This vulnerability is a use-after-free issue in Google Chrome that could allow remote attackers to execute arbitrary code inside the sandbox via crafted HTML pages. While the CVSS score indicates a high severity (8.8), the provided text does not specify direct impacts on compliance with GDPR, HIPAA, or other standards. Compliance risks would depend on how the vulnerability is exploited in a specific environment.

Mitigation Strategies

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