Description OSIDB Bzimport 2025-02-26 03:24:13 UTC 
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.
