How to fix?

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

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-modules-core package and not the kernel-debug-modules-core 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:

iwlwifi: fix use-after-free

If no firmware was present at all (or, presumably, all of the firmware files failed to parse), we end up unbinding by calling device_release_driver(), which calls remove(), which then in iwlwifi calls iwl_drv_stop(), freeing the 'drv' struct. However the new code I added will still erroneously access it after it was freed.

Set 'failure=false' in this case to avoid the access, all data was already freed anyway.
