Summary
Bluetooth: hci_qca: Fix driver shutdown on closed serdev
Details

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

Bluetooth: hci_qca: Fix driver shutdown on closed serdev

The driver shutdown callback (which sends EDLSOCRESET to the device over serdev) should not be invoked when HCI device is not open (e.g. if hcidevopensync() failed), because the serdev and its TTY are not open either. Also skip this step if device is powered off (qcapower_shutdown()).

The shutdown callback causes use-after-free during system reboot with Qualcomm Atheros Bluetooth:
