Overview

CVE-2024-41037 is a medium-severity vulnerability. It was published on July 29, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

ASoC: SOF: Intel: hda: fix null deref on system suspend entry

When system enters suspend with an active stream, SOF core

calls hw_params_upon_resume(). On Intel platforms with HDA DMA used

to manage the link DMA, this leads to 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
