The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to improper reference counting in the NFC pn533 USB driver when handling device disconnection. A local user can disconnect a USB NFC device to cause a dangling reference, leading to a denial of service.

The issue arises because the USB interface reference obtained during driver probe is not properly released upon disconnection.
