CVE-2022-48724

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Fix potential memory leak in intel_setup_irq_remapping() After commit e3beca48a45b ("irqdomain/treewide: Keep firmware node unconditionally allocated"). For tear down scenario, fn is only freed after fail to allocate ir_domain, though it also should be freed in case dmar_enable_qi returns error. Besides free fn, irq_domain and ir_msi_domain need to be removed as well if intel_setup_irq_remapping fails to enable queued invalidation. Improve the rewinding path by add out_free_ir_domain and out_free_fwnode lables per Baolu's suggestion.

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: iommu/vt-d: soluciona una posible pérdida de memoria en intel_setup_irq_remapping() después del commit e3beca48a45b ("irqdomain/treewide: mantiene el nodo de firmware asignado incondicionalmente"). Para el escenario de desmontaje, fn solo se libera después de que no se puede asignar ir_domain, aunque también debe liberarse en caso de que dmar_enable_qi devuelva un error. Además de free fn, irq_domain e ir_msi_domain también deben eliminarse si intel_setup_irq_remapping no logra habilitar la invalidación en cola. Mejore la ruta de rebobinado agregando las etiquetas out_free_ir_domain y out_free_fwnode según la sugerencia de Baolu.
