Overview

CVE-2024-27057 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 1, 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: ipc4-pcm: Workaround for crashed firmware on system suspend

When the system is suspended while audio is active, the

sof_ipc4_pcm_hw_free() is invoked to reset the pipelines since during

suspend the DSP is turned off, streams will be re-started after resume.

If the firmware crashes during while audio is running (or when we reset

the stream before suspend) then the sof_ipc4_set_multi_pipeline_state()

will fail with IPC error and the state change is interrupted.

This will cause misalignment between the kernel and firmware state on next

DSP boot resulting errors returned by firmware for IPC messages, eventually

failing the audio resume.

On stream close the errors are ignored so the kernel state will be

corrected on the next DSP boot, so the second boot after the DSP panic.

If sof_ipc4_trigger_pipelines() is called from sof_ipc4_pcm_hw_free() then

state parameter is SOF_IPC4_PIPE_RESET and only in this case.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
