Description

In the Linux kernel, the following vulnerability has been resolved: net: usb: rtl8150: enable basic endpoint checking Syzkaller reports [1] encountering a common issue of utilizing a wrong usb endpoint type during URB submitting stage. This, in turn, triggers a warning shown below. For now, enable simple endpoint checking (specifically, bulk and interrupt eps, testing control one is not essential) to mitigate the issue with a view to do other related cosmetic changes later, if they are necessary.
