Summary
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 EDL_SOC_RESET to the device
over serdev) should not be invoked when HCI device is not open (e.g. if
hci_dev_open_sync() failed), because the serdev and its TTY are not open
either. Also skip this step if device is powered off
(qca_power_shutdown()).
The shutdown callback causes use-after-free during system reboot with
Qualcomm Atheros Bluetooth:
