CVE-2024-38593

5.5 · MEDIUM
Published Jun 19, 2024 linux CWE-908 EPSS 0.22% (13th pctl)

Overview

CVE-2024-38593 is a medium-severity vulnerability affecting linux linux_kernel. It was published on June 19, 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: micrel: Fix receiving the timestamp in the frame for lan8841

The blamed commit started to use the ptp workqueue to get the second

part of the timestamp. And when the port was set down, then this

workqueue is stopped. But if the config option NETWORK_PHY_TIMESTAMPING

is not enabled, then the ptp_clock is not initialized so then it would

crash when it would try to access the delayed work.

So then basically by setting up and then down the port, it would crash.

The fix consists in checking if the ptp_clock is initialized and only

then cancel the delayed work.

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.
