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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
CWE-20	The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

Attack-Flow Graph

Executive Summary

This vulnerability is a use-after-free issue in Google Chrome's Core component. A use-after-free occurs when a program continues to use a pointer after the memory it points to has been freed. This can lead to arbitrary code execution outside the sandbox, meaning malicious code could run with elevated privileges.

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.

Impact Analysis

An attacker could exploit this by tricking you into visiting a specially crafted HTML page. This could allow them to execute arbitrary code on your system, potentially stealing data, installing malware, or taking control of your device.

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

Update Google Chrome to version 156.0.8078.47 or later immediately. This can be done via the browser's built-in update mechanism or by downloading the latest version from Google's official site.
