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 DWC3GEVNTCOUNT. 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.
