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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Browser component on Windows systems. It allows a remote attacker to execute arbitrary code outside the sandbox by tricking a user into visiting a specially crafted HTML page. The attack leverages social engineering tactics to exploit this memory corruption flaw.

Detection Guidance

Detection of this vulnerability requires checking the version of Google Chrome installed on your system. If your version is prior to 153.0.8010.36, the system is vulnerable. Use the command 'google-chrome --version' on Linux or check 'chrome://settings/help' in the browser to verify the version.

Impact Analysis

This vulnerability can allow an attacker to run malicious code on your computer, potentially stealing data, installing malware, or taking control of your system. Since it bypasses Chrome's sandbox, it has higher privileges than typical browser exploits.

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

Immediately update Google Chrome to version 153.0.8010.36 or later. Disable automatic loading of HTML pages from untrusted sources and avoid opening suspicious links or files to reduce exposure to social engineering attacks.
