Description

In the Linux kernel, the following vulnerability has been resolved: can: mcba_usb: properly check endpoint type Syzbot reported warning in usb_submit_urb() which is caused by wrong endpoint type. We should check that in endpoint is actually present to prevent this warning. Found pipes are now saved to struct mcba_priv and code uses them directly instead of making pipes in place. Fail log: | usb 5-1: BOGUS urb xfer, pipe 3 != type 1 | WARNING: CPU: 1 PID: 49 at drivers/usb/core/urb.c:502 usb_submit_urb+0xed2/0x18a0 drivers/usb/core/urb.c:502 | Modules linked in: | CPU: 1 PID: 49 Comm: kworker/1:2 Not tainted 5.17.0-rc6-syzkaller-00184-g38f80f42147f #0 | Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.14.0-2 04/01/2014 | Workqueue: usb_hub_wq hub_event | RIP: 0010:usb_submit_urb+0xed2/0x18a0 drivers/usb/core/urb.c:502 | ... | Call Trace: | <TASK> | mcba_usb_start drivers/net/can/usb/mcba_usb.c:662 [inline] | mcba_usb_probe+0x8a3/0xc50 drivers/net/can/usb/mcba_usb.c:858 | usb_probe_interface+0x315/0x7f0 drivers/usb/core/driver.c:396 | call_driver_probe drivers/base/dd.c:517 [inline]
