Drivers mimic the behavior of hda_codec_driver_probe/remove() found in sound/pci/hda/hda_bind.c with their component-&gt;probe/remove() instead.</p> <p>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.</p> <p>As ASoC sound card may be unbound without codec device being actually removed from the system, unsetting -&gt;preset in snd_hda_codec_cleanup_for_unbind() interferes with module unload -&gt; load scenario causing null-ptr-deref. Preset is assigned only once, during device/driver matching whereas ASoC codec driver&#39;s module reloading may occur several times throughout the lifetime of an audio stack.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>ALSA: hda: Do not unset preset when cleaning up codec</p> <p>Several functions that take part in codec&#39;s initialization and removal are re-used by ASoC codec drivers implementations.
