Description
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_conn: Use disable_delayed_work_sync This makes use of disable_delayed_work_sync instead cancel_delayed_work_sync as it not only cancel the ongoing work but also disables new submit which is disarable since the object holding the work is about to be freed.
