CVE-2025-22128

Description

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.
