This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

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

Bluetooth: hci_core: cancel all works upon hci_unregister_dev()

syzbot is reporting that calling hci_release_dev() from hci_error_reset()

due to hci_dev_put() from hci_error_reset() can cause deadlock at

destroy_workqueue(), for hci_error_reset() is called from

hdev->req_workqueue which destroy_workqueue() needs to flush.

We need to make sure that hdev->{rx_work,cmd_work,tx_work} which are

queued into hdev->workqueue and hdev->{power_on,error_reset} which are

queued into hdev->req_workqueue are no longer running by the moment

destroy_workqueue(hdev->workqueue);

destroy_workqueue(hdev->req_workqueue);

are called from hci_release_dev().

Call cancel_work_sync() on these work items from hci_unregister_dev()

as soon as hdev->list is removed from hci_dev_list.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
