In the Linux kernel, the following vulnerability has been resolved:
usb-storage: ene_ub6250: fix race between scan work and probe
ene_ub6250_probe() calls usb_stor_probe2(), which starts the usb-storage
infrastructure and schedules the delayed scan work. The driver then
calls ene_get_card_type(), which sends an ENE command through
ene_send_scsi_cmd() and the usb-storage bulk transfer helpers.
Both the delayed scan work, through usb_stor_Bulk_max_lun(), and
ene_get_card_type() use us->current_urb. The scan work serializes this
access with us->dev_mutex, but the ENE card-type probe does not. If the
scan work runs while ene_get_card_type() is still using us->current_urb,
usb_submit_urb() warns that the URB is already active.
Serialize ene_get_card_type() with us->dev_mutex, matching the locking
used by the scan path.
