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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 the Windows Bluetooth Port Driver. It allows an unauthorized attacker to elevate privileges by exploiting a memory corruption issue over an adjacent network.

Detection Guidance

Detection of this vulnerability requires monitoring for unusual Bluetooth driver behavior or unauthorized privilege escalation. Check Windows Event Viewer for Bluetooth-related errors or crashes in the Bluetooth Port Driver. Use PowerShell commands like 'Get-WinEvent -LogName System | Where-Object {$_.Message -like "*Bluetooth*"}' to filter relevant logs.

Impact Analysis

An attacker could gain elevated privileges on your system, potentially leading to unauthorized access, data theft, or further compromise of your device or network.

Compliance Impact

This vulnerability allows unauthorized privilege escalation over an adjacent network, which could lead to unauthorized access to sensitive data. This may violate compliance requirements under GDPR (data protection) and HIPAA (health information security) by enabling unauthorized data access or disclosure.

Mitigation Strategies

Apply the latest Windows security updates from Microsoft to patch the Bluetooth Port Driver vulnerability. Disable Bluetooth services if not in use and monitor network traffic for unusual activity near affected systems.
