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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 is a use-after-free vulnerability in Google Chrome's Fullscreen feature. It occurs when a program tries to use memory that has already been freed, potentially allowing a remote attacker to execute arbitrary code outside the sandbox. The issue is triggered by a crafted HTML page and has been assigned a critical severity rating.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 154.0.8037.57. To detect it, check your Chrome version by running chrome://version/ in the browser address bar. If your version is below 154.0.8037.57, the system is vulnerable.

Impact Analysis

This vulnerability could allow an attacker to run malicious code on your system by tricking you into visiting a specially crafted webpage. Since it can execute code outside the browser sandbox, it may compromise your system's security, steal data, or install malware.

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 risks may impact compliance with GDPR (data protection) and HIPAA (health data security) by potentially exposing sensitive information or violating integrity requirements.

Mitigation Strategies

Update Google Chrome to version 154.0.8037.57 or later to address the use after free vulnerability in Fullscreen mode.
