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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Chromoting (Google Chrome's remote desktop feature) that allows a remote attacker to execute arbitrary code outside the sandbox by sending specially crafted network traffic. The issue exists in Chrome versions before 151.0.7922.173.

Detection Guidance

Detection of CVE-2026-76017 requires checking the installed version of Google Chrome. If your version is prior to 151.0.7922.173, the system is vulnerable. Use commands like 'google-chrome --version' or check via package manager (e.g., 'apt list --installed | grep chrome' on Debian/Ubuntu).

Network traffic analysis may help identify exploitation attempts, but this requires deep packet inspection and is not straightforward.

Impact Analysis

An attacker could exploit this to run malicious code on your system, potentially stealing data, installing malware, or taking control of your device. Since it bypasses the sandbox, it has elevated privileges.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR (data protection) and HIPAA (health information privacy) requirements. Organizations must patch systems to maintain compliance.

Mitigation Strategies

Update Google Chrome to version 151.0.7922.173 or later immediately. Disable automatic updates temporarily if needed, but prioritize patching. Avoid untrusted network traffic until updated.
