Vulnerability from csaf_harmaninternational - Published: 2025-12-10 07:00 - Updated: 2025-12-10 07:00Summary
BLE ICM Vulnerability in JBL Headphones
Severity
6.5 (medium)
Notes
Summary: The BLE controller in certain consumer products fails to properly validate the channel map field in connection requests, enabling attackers within radio range to cause a denial of service through a specially crafted packet.
Impact: Sending an invalid connection request to a JBL Bluetooth Speaker causes it to crash or enter a deadlock state, halting music playback and disconnecting existing connections. Recovery requires manual reboot by the user, as reconnection is impossible in this state.
Remediation: No remediation is available as of now. A manual reboot of the device by the user is required to restore functionality.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
