Description

usb: dwc3: gadget: check that event count does not exceed event buffer length

In the Linux kernel, the following vulnerability has been resolved:

usb: dwc3: gadget: check that event count does not exceed event buffer length

The event count is read from register DWC3_GEVNTCOUNT.

There is a check for the count being zero, but not for exceeding the

event buffer length.

Check that event count does not exceed event buffer length,

avoiding an out-of-bounds access when memcpy'ing the event.
