  "description": "In the Linux kernel, the following vulnerability has been resolved:  ALSA: hda: Do not unset preset when cleaning up codec  Several functions that take part in codec\u0027s initialization and removal are re-used by ASoC codec drivers implementations. Drivers mimic the behavior of hda_codec_driver_probe/remove() found in sound/pci/hda/hda_bind.c with their component-\u003Eprobe/remove() instead.  One of the reasons for that is the expectation of snd_hda_codec_device_new() to receive a valid pointer to an instance of struct snd_card. This expectation can be met only once sound card components probing commences.  As ASoC sound card may be unbound without codec device being actually removed from the system, unsetting -\u003Epreset in snd_hda_codec_cleanup_for_unbind() interferes with module unload -\u003E load scenario causing null-ptr-deref. Preset is assigned only once, during device/driver matching whereas ASoC codec driver\u0027s module reloading may occur several times throughout the lifetime of an audio stack.",
