A fix is available — apply it.

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

media: rc: igorplugusb: heed coherency rules

In a control request, the USB request structure can be subject to DMA on some HCs. Hence it must obey the rules for DMA coherency. Allocate it separately.
