Description
A vulnerability was found in the usb_parse_endpoint() function in the Linux kernel's usb drivers, where improper handling of the reserved bits in an endpoint descriptor's bEndpointAddress field can lead to confusion in the endpoint_is_duplicate() routine in config.c. This will erroneously treat the same endpoint descriptors as distinct, given that the reserved bits are not properly cleared. This can potentially lead to unexpected behavior from connected USB devices.
