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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 the TabStrip component of Google Chrome versions prior to 155.0.8059.39. 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 tricking a user into visiting a specially crafted HTML page, enabling them to execute arbitrary code outside the browser's sandbox.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 155.0.8059.39. To detect it, check your Chrome version via chrome://settings/help or command line. If outdated, update Chrome immediately. No direct detection commands exist as it requires analyzing memory corruption patterns.

Impact Analysis

This vulnerability could allow an attacker to run malicious code on your computer. If you visit a compromised or malicious website, the attacker might take control of your browser, steal sensitive data, install malware, or perform other harmful actions. The impact is high because the exploit can bypass the browser's sandbox, giving the attacker more control over your system.

Compliance Impact

This vulnerability allows arbitrary code execution outside 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 security) 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 TabStrip.
