For tear down scenario, fn is only freed\nafter fail to allocate ir_domain, though it also should be freed in case\ndmar_enable_qi returns error.\n\nBesides free fn, irq_domain and ir_msi_domain need to be removed as well\nif intel_setup_irq_remapping fails to enable queued invalidation.\n\nImprove the rewinding path by add out_free_ir_domain and out_free_fwnode\nlables per Baolu's suggestion."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: iommu/vt-d: soluciona una posible p\u00e9rdida de memoria en intel_setup_irq_remapping() despu\u00e9s del commit e3beca48a45b (\"irqdomain/treewide: mantiene el nodo de firmware asignado incondicionalmente\"). Para el escenario de desmontaje, fn solo se libera despu\u00e9s de que no se puede asignar ir_domain, aunque tambi\u00e9n debe liberarse en caso de que dmar_enable_qi devuelva un error. Adem\u00e1s de free fn, irq_domain e ir_msi_domain tambi\u00e9n deben eliminarse si intel_setup_irq_remapping no logra habilitar la invalidaci\u00f3n en cola. Mejore la ruta de rebobinado agregando las etiquetas out_free_ir_domain y out_free_fwnode seg\u00fan la sugerencia de Baolu."
