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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Google Chrome's Receiver component. It occurs when a program continues to use memory after it has been freed, potentially leading to arbitrary code execution outside the sandbox. The issue is triggered by specially crafted network traffic and affects Chrome versions before 153.0.8010.36.

Detection Guidance

Detection of this vulnerability requires checking the version of Google Chrome installed on your system. If the version is prior to 153.0.8010.36, 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).

Network traffic analysis may help identify crafted packets exploiting this flaw, but specific detection commands are not provided in the given context.

Impact Analysis

An attacker could exploit this to execute malicious code on your system, bypassing Chrome's security sandbox. This could allow them to install malware, steal data, or take control of your device. The risk comes from visiting a malicious website or receiving crafted network traffic.

Compliance Impact

This vulnerability allows arbitrary code execution outside the sandbox via crafted network traffic, which could lead to unauthorized access to sensitive data. Such access may violate GDPR's data protection requirements and HIPAA's safeguards for protected health information if exploited.

Mitigation Strategies

Update Google Chrome to version 153.0.8010.36 or later to address the use after free vulnerability in Receiver.
