How to fix?

Upgrade RHEL:9 kernel-rt to version 0:5.14.0-284.79.1.rt14.364.el9_2 or higher.
This issue was patched in RHSA-2024:5365.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt package and not the kernel-rt package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

nfp: flower: handle acti_netdevs allocation failure

The kmalloc_array() in nfp_fl_lag_do_work() will return null, if the physical memory has run out. As a result, if we dereference the acti_netdevs, the null pointer dereference bugs will happen.

This patch adds a check to judge whether allocation failure occurs. If it happens, the delayed work will be rescheduled and try again.
