Technical description

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_sync: Fix queuing commands when HCI_UNREGISTER is set

hci_cmd_sync_queue shall return an error if HCI_UNREGISTER flag has

been set as that means hci_unregister_dev has been called so it will

likely cause a uaf after the timeout as the hdev will be freed.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
