A use-after-free flaw caused by a race among the superblock operations in
the gadgetfs Linux driver was found. It could be triggered by yanking out a
device that is running the gadgetfs side.

Notes

Author Note
sbeattie Because the USB gadget interface is for when the system is acting as a USB device rather than a host, the USB Gadget FS is not mounted by default in Ubuntu.
