CVE-2024-38553

5.5 · MEDIUM
Published Jun 19, 2024 linux CWE-667 EPSS 0.19% (9th pctl)

Overview

CVE-2024-38553 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: fec: remove .ndo_poll_controller to avoid deadlocks

There is a deadlock issue found in sungem driver, please refer to the

commit ac0a230f719b ("eth: sungem: remove .ndo_poll_controller to avoid

deadlocks"). The root cause of the issue is that netpoll is in atomic

context and disable_irq() is called by .ndo_poll_controller interface

of sungem driver, however, disable_irq() might sleep. After analyzing

the implementation of fec_poll_controller(), the fec driver should have

the same issue. Due to the fec driver uses NAPI for TX completions, the

.ndo_poll_controller is unnecessary to be implemented in the fec driver,

so fec_poll_controller() can be safely removed.

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.
