CVE-2026-45996

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

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.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
