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

Bluetooth: btrtl: fix out of bounds memory access

The problem is detected by KASAN. btrtl driver uses private hci data to store 'struct btrealtekdata'. If btrtl driver is used with btusb, then memory for private hci data is allocated in btusb. But no private data is allocated after hcidev, when btrtl is used with hci_h5.

This commit adds memory allocation for hci_h5 case.
