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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Google Chrome's Extensions component on Mac. It allows a remote attacker to execute arbitrary code outside the sandbox by tricking a user into visiting a specially crafted HTML page. The flaw occurs when the program tries to use memory that has already been freed, leading to potential code execution.

Detection Guidance

This vulnerability is specific to Google Chrome on Mac prior to version 153.0.8010.36. Detection involves checking the installed Chrome version. If your version is below 153.0.8010.36, the system is vulnerable. Use the command 'google-chrome --version' to check the installed version on Mac systems.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your computer, bypassing security restrictions. This could lead to unauthorized access to your data, installation of malware, or complete system compromise. Users on Mac systems with vulnerable Chrome versions are at risk.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code outside the sandbox via crafted HTML pages, which could lead to unauthorized data access or manipulation. Such code execution risks may violate GDPR's integrity and confidentiality requirements or HIPAA's safeguards for protected health information if exploited.

Mitigation Strategies

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