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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 V8, the JavaScript engine used by Google Chrome. It occurs when a program continues to use memory after it has been freed, potentially leading to arbitrary code execution within the sandbox. An attacker could exploit this by crafting a malicious HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 155.0.8059.39. To detect it, check your Chrome version by running chrome://version/ in the browser. If your version is below 155.0.8059.39, the system is vulnerable. Update Chrome immediately to the latest version to mitigate the risk.

Impact Analysis

If exploited, this vulnerability could allow a remote attacker to run arbitrary code on your system through a specially crafted webpage. This could lead to unauthorized access, data theft, or installation of malware, even within the browser's sandbox.

Compliance Impact

This vulnerability allows remote code execution inside the sandbox via a crafted HTML page, which could lead to unauthorized data access or manipulation. Such risks may impact compliance with GDPR (data protection) and HIPAA (health data privacy) by potentially exposing sensitive user data or violating confidentiality requirements.

Mitigation Strategies

Update Google Chrome to version 155.0.8059.39 or later to address the use-after-free vulnerability in V8.
