Description:
 go7007_snd_init in drivers/media/usb/go7007/snd-go7007.c in the Linux
 kernel before 5.6 does not call snd_card_free for a failure path, which
 causes a memory leak, aka CID-9453264ef586.
Ubuntu-Description:
 Chuhong Yuan discovered that go7007 USB audio device driver in the Linux
 kernel did not properly deallocate memory in some failure conditions. A
 physically proximate attacker could use this to cause a denial of service
 (memory exhaustion).
