How to fix?

There is no fixed version for Centos:9 kernel-rt-debug-modules-extra.

NVD Description

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

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

Revert "wifi: mac80211: fix memory leak in ieee80211_if_add()"

This reverts commit 13e5afd3d773c6fc6ca2b89027befaaaa1ea7293.

ieee80211_if_free() is already called from free_netdev(ndev) because ndev->priv_destructor == ieee80211_if_free
