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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Core component. It allows a remote attacker to execute arbitrary code outside the sandbox by tricking a user into installing a malicious Chrome extension. The attack leverages social engineering to exploit this memory corruption flaw.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 153.0.8010.36. Detection involves checking the installed Chrome version. Use commands like 'google-chrome --version' on Linux or check 'chrome://settings/help' in the browser. If the version is below 153.0.8010.36, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your system, potentially stealing data, installing malware, or taking control of your device. Since it bypasses sandbox protections, the impact is severe and could compromise your privacy and security.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code outside the sandbox via crafted Chrome extensions, which could lead to unauthorized data access or manipulation. This may violate GDPR's data protection requirements and 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 Core.
