Description
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Cancel pending work at closing a MIDI substream
At closing a USB MIDI output substream, there might be still a pending
work, which would eventually access the rawmidi runtime object that is
being released. For fixing the race, make sure to cancel the pending
work at closing.
