[Impact]

 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.

[Fix]

Mantic:	Clean cherry-pick from linux-6.6.y
Jammy:	pending
Focal:	Mantic patch applied cleanly
Bionic:	not-affected
Xenial:	not-affected
Trusty:	not-affected

[Test Case]

Compile and boot tested.

[Where problems could occur]

This fix affects those who use Bluetooth HCI, an issue with this fix
would be visable to the user via corrupted data or unexpected system
behavior.
