Description

A flaw was found in the Linux kernel's USB MIDI 2.0 gadget function. When the MIDI 2.0 gadget is configured with a specific input block direction, an endpoint may not be properly initialized. During subsequent endpoint cleanup, an attempt to access this uninitialized endpoint can lead to a null-pointer dereference, resulting in a system crash. This vulnerability could allow an attacker to cause a denial of service (DoS).
