What it is

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

media: rc: igorplugusb: fix control request setup packet

Commit eac69475b01f ("media: rc: igorplugusb: heed coherency

rules") changed the control request storage from an embedded struct to

an allocated pointer so it can obey DMA coherency rules.

However, the driver still passes &ir->request to usb_fill_control_urb().

That points the URB setup packet at the pointer field itself rather than

at the allocated struct usb_ctrlrequest.

USB core then interprets pointer bytes as the setup packet. This can

produce an invalid bRequestType and trigger the control direction warning

reported by syzbot:

usb 2-1: BOGUS control dir, pipe 80003580 doesn't match bRequestType 0

Pass ir->request itself as the setup packet.
