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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 the Bookmarks feature of Google Chrome versions before 156.0.8078.47. A use-after-free occurs when a program continues to use memory after it has been freed, potentially leading to arbitrary code execution. In this case, a remote attacker could exploit this by crafting a malicious HTML page to trigger the flaw, allowing them to execute arbitrary code within the browser's sandbox.

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. 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 specially crafted webpage. This could lead to unauthorized access to your data, installation of malware, or other malicious activities. However, the sandbox limits the impact to the browser environment.

Compliance Impact

This vulnerability allows a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. This could lead to unauthorized access to sensitive data, which may violate compliance requirements under GDPR and HIPAA if personal or health information is exposed.

Mitigation Strategies

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