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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Chromecast within Google Chrome before version 153.0.8010.36. A use-after-free occurs when a program continues to use a pointer after freeing the memory it points to, potentially leading to arbitrary code execution. An attacker could exploit this by tricking a user into visiting a specially crafted HTML page, allowing them to run code within the sandboxed environment.

Detection Guidance

Detection of this vulnerability requires checking the installed version of Google Chrome. If the version is prior to 153.0.8010.36, the system is vulnerable. Use commands like 'google-chrome --version' or check via package manager (e.g., 'apt list --installed | grep chrome' on Debian-based systems).

Impact Analysis

If exploited, this vulnerability could allow a remote attacker to execute arbitrary code on your system. Since it affects Chromecast in Chrome, visiting a malicious webpage might compromise the sandbox, enabling the attacker to take control of your browser or device. This could lead to data theft, installation of malware, or further network intrusions.

Compliance Impact

This vulnerability allows remote code execution inside a sandbox via a crafted HTML page, which could lead to unauthorized access or data breaches. Such breaches may violate GDPR (data protection) or HIPAA (health data privacy) if sensitive user data is exposed or mishandled.

Mitigation Strategies

Update Google Chrome to version 153.0.8010.36 or later immediately. Disable Chromecast functionality if not needed. Avoid visiting untrusted websites until the update is applied.
