Title
s390/pci: Fix duplicate pci_dev_put() in disable_slot() when PF has child VFs
Summary
In the Linux kernel, the following vulnerability has been resolved: s390/pci: Fix duplicate pci_dev_put() in disable_slot() when PF has child VFs With commit bcb5d6c76903 ("s390/pci: introduce lock to synchronize state of zpci_dev's") the code to ignore power off of a PF that has child VFs was changed from a direct return to a goto to the unlock and pci_dev_put() section. The change however left the existing pci_dev_put() untouched resulting in a doubple put. This can subsequently cause a use after free if the struct pci_dev is released in an unexpected state. Fix this by removing the extra pci_dev_put().
Severity

Con el commit bcb5d6c76903 (\"s390/pci: introducir un bloqueo para sincronizar el estado de zpci_dev\"), el c\u00f3digo para ignorar el apagado de un PF con VFs secundarios se cambi\u00f3 de un retorno directo a un goto a la secci\u00f3n de desbloqueo y pci_dev_put(). Sin embargo, el cambio dej\u00f3 intacto el pci_dev_put() existente, lo que result\u00f3 en un doble put. Esto puede provocar un use after free si la estructura pci_dev se libera en un estado inesperado. Se soluciona eliminando el pci_dev_put() adicional."
