In the Linux kernel, the following vulnerability has been resolved:Input: aiptek - properly check endpoint typeSyzbot reported warning in usb_submit_urb() which is caused by wrongendpoint type. There was a check for the number of endpoints, but notfor the type of endpoint.Fix it by replacing old desc.bNumEndpoints check withusb_find_common_endpoints() helper for finding endpointsFail log:usb 5-1: BOGUS urb xfer, pipe 1 != type 3WARNING: CPU: 2 PID: 48 at drivers/usb/core/urb.c:502 usb_submit_urb+0xed2/0x18a0 drivers/usb/core/urb.c:502Modules linked in:CPU: 2 PID: 48 Comm: kworker/2:2 Not tainted 5.17.0-rc6-syzkaller-00226-g07ebd38a0da2 #0Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.14.0-2 04/01/2014Workqueue: usb_hub_wq hub_event...Call Trace: <TASK> aiptek_open+0xd5/0x130 drivers/input/tablet/aiptek.c:830 input_open_device+0x1bb/0x320 drivers/input/input.c:629 kbd_connect+0xfe/0x160 drivers/tty/vt/keyboard.c:1593
