In the Linux kernel, the following vulnerability has been resolved:

spi: cadence-quadspi: Implement refcount to handle unbind during busy

driver support indirect read and indirect write operation with

assumption no force device removal(unbind) operation. However

force device removal(removal) is still available to root superuser.

Unbinding driver during operation causes kernel crash. This changes

ensure driver able to handle such operation for indirect read and

indirect write by implementing refcount to track attached devices

to the controller and gracefully wait and until attached devices
