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’s 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->probe/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
->preset in snd_hda_codec_cleanup_for_unbind() interferes with module
unload -> load scenario causing null-ptr-deref. Preset is assigned only
once, during device/driver matching whereas ASoC codec driver’s module
reloading may occur several times throughout the lifetime of an audio
stack.
