Published Jul 10, 2024 linux CWE-908 EPSS 0.21% (11th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-39491 is a medium-severity vulnerability affecting linux linux_kernel. It was published on July 10, 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:

ALSA: hda: cs35l56: Fix lifetime of cs_dsp instance

The cs_dsp instance is initialized in the driver probe() so it

should be freed in the driver remove(). Also fix a missing call

to cs_dsp_remove() in the error path of cs35l56_hda_common_probe().

The call to cs_dsp_remove() was being done in the component unbind

callback cs35l56_hda_unbind(). This meant that if the driver was

unbound and then re-bound it would be using an uninitialized cs_dsp

instance.

It is best to initialize the cs_dsp instance in probe() so that it

can return an error if it fails. The component binding API doesn't

have any error handling so there's no way to handle a failure if

cs_dsp was initialized in the bind.

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.
