A fix is available — apply it.

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

spi: imx: fix use-after-free on unbind

The SPI subsystem frees the controller and any subsystem allocated driver data as part of deregistration (unless the allocation is device managed).

Take another reference before deregistering the controller so that the driver data is not freed until the driver is done with it.
