Description Summary:
A Use-After-Free vulnerability in the OpenSynergy BlueSDK Bluetooth stack allows for potential remote code execution due to improper object validation.
Executive Summary:
A critical Use-After-Free vulnerability in the OpenSynergy BlueSDK (6.x and earlier) presents a significant risk of remote code execution through the Bluetooth stack.
Vulnerability Details
CVE-ID: CVE-2024-45434
Affected Software: OpenSynergy BlueSDK
Affected Versions: 6.x and earlier
Vulnerability: The flaw is a Use-After-Free condition occurring within the Bluetooth stack, triggered by the lack of validation for object existence. This vulnerability is reachable over the network and does not require authentication.
Business Impact
With a CVSS score of 9.8, this vulnerability poses a severe threat, as it allows attackers to potentially execute arbitrary code on affected devices. Given that BlueSDK is often embedded in automotive or IoT hardware, the impact could range from service disruption to full device takeover and potential safety risks in connected systems.
Remediation Plan
Immediate Action: Contact the vendor or consult the OpenSynergy Security Portal to obtain the latest firmware or SDK patch corresponding to your integration.
Proactive Monitoring: Monitor for unexpected device reboots or crashes, which may indicate attempts to trigger the Use-After-Free condition.
Compensating Controls: Where feasible, disable Bluetooth functionality on affected devices if it is not strictly required for current operational needs.
Exploitation Status
Public Exploit Available: Unknown
Analyst Notes: As of Sep 12, 2025, there is no confirmed active exploitation in the wild; however, per CISA's SSVC assessment a proof-of-concept exists, so exploitation risk should be treated as credible. Use-After-Free vulnerabilities in network stacks are inherently complex and often represent high-value targets for advanced threat actors.
Analyst Recommendation
This vulnerability represents a critical security defect in embedded Bluetooth stacks. Organizations utilizing OpenSynergy BlueSDK must coordinate with their hardware integrators to identify and apply the necessary patches as soon as they become available.
