Description
In the Linux kernel, the following vulnerability has been resolved:
PCI: endpoint: Fix PCI domain ID release in pci_epc_destroy()
pci_epc_destroy() invokes pci_bus_release_domain_nr() to release the PCI
domain ID, but there are two issues:
- 'epc->dev' is passed to pci_bus_release_domain_nr() which was already
freed by device_unregister(), leading to a use-after-free issue.
- Domain ID corresponds to the EPC device parent, so passing 'epc->dev'
is also wrong.
Fix these issues by passing 'epc->dev.parent' to
pci_bus_release_domain_nr() and also do it before device_unregister().
