Overview

CVE-2024-49871 is a medium-severity vulnerability. It was published on October 21, 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:

Input: adp5589-keys - fix NULL pointer dereference

We register a devm action to call adp5589_clear_config() and then pass

the i2c client as argument so that we can call i2c_get_clientdata() in

order to get our device object. However, i2c_set_clientdata() is only

being set at the end of the probe function which means that we'll get a

NULL pointer dereference in case the probe function fails early.

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.
