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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 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 outside the sandbox. The attacker could exploit this by tricking a user into installing a malicious Chrome extension.

Detection Guidance

This vulnerability involves a use-after-free issue in Google Chrome's Extensions component. Detection primarily requires checking the installed Chrome version and reviewing installed extensions for suspicious activity. No direct network or system commands are provided in the CVE details. Ensure Chrome is updated to version 152.0.7977.65 or later to mitigate the risk.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your system outside Chrome's security sandbox. This might lead to unauthorized access to your data, installation of malware, or other malicious activities while bypassing normal security restrictions.

Compliance Impact

This vulnerability involves a use-after-free issue in Google Chrome's Extensions component, which could allow a remote attacker to execute arbitrary code outside the sandbox via a crafted extension. Such arbitrary code execution could lead to unauthorized access to sensitive data, potentially violating GDPR's data protection requirements or HIPAA's safeguards for protected health information if exploited.

Mitigation Strategies

Update Google Chrome to version 152.0.7977.65 or later to address the use after free vulnerability in Extensions.
