Overview

About vulnerability

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.
