CVE-2024-50051

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

spi: mpc52xx: Add cancel_work_sync before module remove

If we remove the module which will call mpc52xx_spi_remove
it will free 'ms' through spi_unregister_controller.
while the work ms->work will be used. The sequence of operations
that may lead to a UAF bug.

Fix it by ensuring that the work is canceled before proceeding with
the cleanup in mpc52xx_spi_remove.

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
