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().
