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_submit_urb+0x13a5/0x1970 drivers/usb/core/urb.c:410
Modules linked in:

Call Trace:
<TASK>
usb_start_wait_urb+0x113/0x530 drivers/usb/core/message.c:58
usb_internal_control_msg drivers/usb/core/message.c:102 [inline]
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.
