## Overview

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

ALSA: usb: Fix UAF at delayed release of MIDI2 EPs

The recent fix for UAF in ump_to_endpoint() caused another UAF because
it tries to dereference the UMP endpoint object, but this might be
executed at a delayed context where the endpoint has been already
released.

Add private_free to clear the associated data for avoiding the further
dereference for delayed releases.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
