Overview

CVE-2024-42089 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: fsl-asoc-card: set priv->pdev before using it

priv->pdev pointer was set after being used in

fsl_asoc_card_audmux_init().

Move this assignment at the start of the probe function, so

sub-functions can correctly use pdev through priv.

fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the

dev struct, used with dev_err macros.

As priv is zero-initialised, there would be a NULL pointer dereference.

Note that if priv->dev is dereferenced before assignment but never used,

for example if there is no error to be printed, the driver won't crash

probably due to compiler optimisations.

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.
