Pending analysis
Type:
CWE-476 NULL Pointer Dereference

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ASoC: SOF: Intel: hda: fix null deref on system suspend entry<br /> <br /> When system enters suspend with an active stream, SOF core<br /> calls hw_params_upon_resume(). On Intel platforms with HDA DMA used<br /> to manage the link DMA, this leads to call chain of<br /> <br /> hda_dsp_set_hw_params_upon_resume()<br /> -&gt; hda_dsp_dais_suspend()<br /> -&gt; hda_dai_suspend()<br /> -&gt; hda_ipc4_post_trigger()<br /> <br /> A bug is hit in hda_dai_suspend() as hda_link_dma_cleanup() is run first,<br /> which clears hext_stream-&gt;link_substream, and then hda_ipc4_post_trigger()<br /> is called with a NULL snd_pcm_substream pointer.
