Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
Input: aiptek - properly check endpoint type
Syzbot reported warning in usb_submit_urb() which is caused by wrong endpoint type. There was a check for the number of endpoints, but not for the type of endpoint.
Fix it by replacing old desc.bNumEndpoints check with usb_find_common_endpoints() helper for finding endpoints
Fail log:
usb 5-1: BOGUS urb xfer, pipe 1 != type 3
