CVE-2025-37946

In the Linux kernel, the following vulnerability has been resolved:

s390/pci: Fix duplicate pcidevput() in disable_slot() when PF has child VFs

With commit bcb5d6c76903 ("s390/pci: introduce lock to synchronize state of zpcidev'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 pcidevput() section. The change however left the existing pcidevput() untouched resulting in a doubple put. This can subsequently cause a use after free if the struct pcidev is released in an unexpected state. Fix this by removing the extra pcidevput().
