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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 WebAppInstalls component of Google Chrome on Android. It allows a remote attacker to execute arbitrary code within the browser's sandbox by tricking a user into visiting a specially crafted HTML page. The flaw occurs when the program attempts to use memory that has already been freed, leading to potential memory corruption and arbitrary code execution.

Detection Guidance

This vulnerability is specific to Google Chrome on Android prior to version 156.0.8078.47. Detection involves checking the installed Chrome version. Use the command 'dumpsys package com.android.chrome | grep versionCode' on Android to verify the version. If the version is below 156.0.8078.47, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow an attacker to run malicious code on your device through a crafted webpage. This could lead to unauthorized access to your data, installation of malware, or further compromise of your system. The sandbox limits the impact, but successful exploitation could still result in significant security risks.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code inside the sandbox via crafted HTML pages. Such arbitrary code execution could lead to unauthorized access to sensitive data, which may violate compliance requirements under GDPR (data protection) and HIPAA (health information privacy).

Mitigation Strategies

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