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:

wifi: ath12k: Clear affinity hint before calling ath12k_pci_free_irq() in error path

If a shared IRQ is used by the driver due to platform limitation, then the IRQ affinity hint is set right after the allocation of IRQ vectors in ath12k_pci_msi_alloc(). This does no harm unless one of the functions requesting the IRQ fails and attempt to free the IRQ.

This may end up with a warning from the IRQ core that is expecting the affinity hint to be cleared before freeing the IRQ:

kernel/irq/manage.c:

/* make sure affinity_hint is cleaned up */
if (WARN_ON_ONCE(desc->affinity_hint))
    desc->affinity_hint = NULL;

So to fix this issue, clear the IRQ affinity hint before calling ath12k_pci_free_irq() in the error path. The affinity will be cleared once again further down the error path due to code organization, but that does no harm.
