Description
A vulnerability was found in the Linux kernel, affecting Intel platforms using HDA DMA to manage the link DMA. When the system enters a suspend mode with an active stream, it can trigger a chain of function calls including hda_dai_suspend(), which calls the function hda_link_dma_cleanup() that clears the hext_stream->link_substream. However, afterwards the hda_ipc4_post_trigger() function is called and attempts to use the now-cleared snd_pcm_susbtream pointer, causing a NULL pointer dereference, potentially leading to system instability.
