Exploitability

CWE

KEV

CWE ID	Description
CWE-863	The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Actor component of Google Chrome before version 156.0.8078.47. 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 crafting a malicious HTML page to trigger the flaw.

Detection Guidance

Detection of this vulnerability requires checking the version of Google Chrome installed on your system. If the version is prior to 156.0.8078.47, the system is vulnerable. Use commands like 'google-chrome --version' or check via package manager (e.g., 'apt list --installed | grep chrome' for Debian-based systems).

Impact Analysis

This vulnerability could allow a remote attacker to execute arbitrary code on your system if you visit a specially crafted malicious webpage. Since it occurs inside the sandbox, the impact is somewhat limited, but it could still lead to unauthorized code execution or data theft depending on the attacker's goals.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code inside 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 user data or violating confidentiality requirements.

Mitigation Strategies

Update Google Chrome to version 156.0.8078.47 or later to address the use after free vulnerability in Actor.
