Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: rc: igorplugusb: fix control request setup packet<br /> <br /> Commit eac69475b01f ("media: rc: igorplugusb: heed coherency<br /> rules") changed the control request storage from an embedded struct to<br /> an allocated pointer so it can obey DMA coherency rules.<br /> <br /> However, the driver still passes &amp;ir-&gt;request to usb_fill_control_urb().<br /> That points the URB setup packet at the pointer field itself rather than<br /> at the allocated struct usb_ctrlrequest.<br /> <br /> USB core then interprets pointer bytes as the setup packet. This can<br /> produce an invalid bRequestType and trigger the control direction warning<br /> reported by syzbot:<br /> <br /> usb 2-1: BOGUS control dir, pipe 80003580 doesn&amp;#39;t match bRequestType 0<br /> <br /> Pass ir-&gt;request itself as the setup packet.
