CVE-2024-41037

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A bug has been resolved in the Linux kernel related to a null dereference on system suspend entry. When the system enters suspend with an active stream, the SOF core calls hw params upon resume(). On Intel platforms with HDA DMA used to manage the link DMA, this leads to a call chain of hda dsp set hw params upon resume() -> hda dsp dais suspend() -> hda dai suspend() -> hda ipc4 post trigger(). A bug is hit in hda dai suspend() as hda link dma cleanup() is run first, which clears hext stream->link substream, and then hda ipc4 post trigger() is called with a NULL snd pcm substream pointer.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
