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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Google Chrome's Extensions component. It occurs when a program tries to use memory that has already been freed, potentially allowing a remote attacker to execute arbitrary code within the browser's sandbox. The attacker would need to trick a user into visiting a specially crafted HTML page to exploit this flaw.

Detection Guidance

Detection of CVE-2026-113105 requires checking the installed version of Google Chrome. If your 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

If exploited, this vulnerability could allow an attacker to run malicious code on your device through the Chrome browser. This might lead to unauthorized access to your data, installation of malware, or other malicious activities while bypassing Chrome's security sandbox protections.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code inside the sandbox via crafted HTML pages. This could lead to unauthorized data access, modification, or exfiltration, which may violate GDPR (data protection) and HIPAA (health data security) requirements for safeguarding sensitive information.

Mitigation Strategies

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