Overview

CVE-2024-46856 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 27, 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:

net: phy: dp83822: Fix NULL pointer dereference on DP83825 devices

The probe() function is only used for DP83822 and DP83826 PHY,

leaving the private data pointer uninitialized for the DP83825 models

which causes a NULL pointer dereference in the recently introduced/changed

functions dp8382x_config_init() and dp83822_set_wol().

Add the dp8382x_probe() function, so all PHY models will have a valid

private data pointer to fix this issue and also prevent similar issues

in the future.

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.
