Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: fix use-after-free on marvell probe failure
Make sure to stop any TX URBs submitted during Marvell OOB wakeup
configuration on later probe failures to avoid use-after-free in the
completion callback.
This issue was reported by Sashiko while reviewing a fix for a wakeup
source leak in the btusb probe errors paths.
