Summary
soc: xilinx: Shutdown and free rx mailbox channel
Details

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

soc: xilinx: Shutdown and free rx mailbox channel

A mbox rx channel is requested using mbox_request_channel_byname() in probe. In remove callback, the rx mailbox channel is cleaned up when the rx_chan is NULL due to incorrect condition check. The mailbox channel is not shutdown and it can receive messages even after the device removal. This leads to use after free. Also the channel resources are not freed. Fix this by checking the rx_chan correctly.
