Exploitability

CWE

KEV

CWE ID	Description
CWE-451	The user interface (UI) does not properly represent critical information to the user, allowing the information - or its source - to be obscured or spoofed. This is often a component in phishing attacks.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 SiteIsolation in 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 corruption or arbitrary code execution. In this case, a remote attacker could exploit this by crafting a malicious HTML page to trigger the flaw.

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, update Chrome immediately. No direct network detection commands are provided as this is a client-side issue.

Impact Analysis

If exploited, this vulnerability could allow a remote attacker to execute arbitrary code on your system, potentially taking control of your browser or device. Since it occurs inside the sandbox, the impact is somewhat limited, but successful exploitation could still compromise user data or enable further attacks.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code inside the sandbox via crafted HTML pages, which could lead to unauthorized data access or manipulation. Such risks may impact compliance with GDPR (data protection) and HIPAA (healthcare data privacy) by potentially exposing sensitive user or patient information.

Mitigation Strategies

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