The Linux kernel through 6.1.9 has a Use-After-Free in bigben_remove in
drivers/hid/hid-bigbenff.c via a crafted USB device because the LED
controllers remain registered for too long.

Notes

Author Note
sbeattie requires the removal of the device to exploit, usually implying physical access. upstream submission claims the issue was introduced in 4eb1b01de5b9 (“HID: hid-bigbenff: fix race condition for scheduled work during removal”), which may also have a security impact.
