CVE-2025-22128
Full vulnerability record from the local CVENow database.
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.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: ath12k: Borrar la sugerencia de afinidad antes de llamar a ath12k_pci_free_irq() en la ruta de error Si el controlador usa una IRQ compartida debido a una limitación de la plataforma, la sugerencia de afinidad de IRQ se establece justo después de la asignación de vectores de IRQ en ath12k_pci_msi_alloc(). Esto no causa daño a menos que una de las funciones que solicita la IRQ falle e intente liberarla. Esto puede terminar con una advertencia del núcleo de IRQ que espera que se borre la sugerencia de afinidad antes de liberar la IRQ: kernel/irq/manage.c: /* asegúrese de que affinity_hint se limpie */ if (WARN_ON_ONCE(desc->affinity_hint)) desc->affinity_hint = NULL; Para solucionar este problema, borre la indicación de afinidad de IRQ antes de llamar a ath12k_pci_free_irq() en la ruta de error. La afinidad se borrará más adelante en la ruta de error debido a la organización del código, pero esto no perjudica."
