Alert meAnalysisAIv1 – Mar 12, 2026
Privilege escalation in the Windows Bluetooth RFCOM Protocol Driver across Windows 11 26h1, Windows Server 2025, and Windows 10 1809 stems from improper synchronization of concurrent access to shared resources. An authenticated local attacker can exploit this race condition to gain elevated privileges on affected systems. No patch is currently available for this vulnerability.

DescriptionCVE.org
Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Bluetooth RFCOM Protocol Driver allows an authorized attacker to elevate privileges locally.
Executive ViewAI
A race condition vulnerability in Windows Bluetooth RFCOM Protocol Driver (CVE-2026-23671) allows authorized local users to escalate privileges to system level, potentially enabling attackers to gain complete control of affected devices. This poses a significant risk to organizations with Windows endpoints using Bluetooth connectivity, particularly in BYOD environments or where privileged access is critical.
Disable Bluetooth functionality on endpoints where not operationally required; restrict Bluetooth device pairing to pre-authorized devices only; implement application whitelisting to prevent unauthorized executable execution; enforce principle of least privilege to limit local user account capabilities; deploy EDR solutions with privilege escalation detection; implement audit logging for Bluetooth driver activity and privilege escalation attempts; restrict physical access to vulnerable systems in shared environments.
Threat Intelligence Overview
How this decision was reached
The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
Race conditions occur when multiple concurrent requests exploit the brief time gap between checking a condition and acting upon it (TOCTOU - Time of Check, Time of Use).
