Descriptions

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

usb: usbtmc: Fix bug in pipe direction for control transfers

The syzbot fuzzer reported a minor bug in the usbtmc driver:

usb 5-1: BOGUS control dir, pipe 80001e80 doesn't match bRequestType 0
WARNING: CPU: 0 PID: 3813 at drivers/usb/core/urb.c:412

usb_control_msg+0x2a5/0x4b0 drivers/usb/core/message.c:153
usbtmc_ioctl_request drivers/usb/class/usbtmc.c:1947 [inline]

The problem is that usbtmc_ioctl_request() uses usb_rcvctrlpipe() for
all of its transfers, whether they are in or out. It's easy to fix.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: usbtmc: corrige un error en la dirección de la tubería para las transferencias de control.
