Description

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_core: Fix possible buffer overflow struct hci_dev_info has a fixed size name[8] field so in the event that hdev->name is bigger than that strcpy would attempt to write past its size, so this fixes this problem by switching to use strscpy.
