In the Linux kernel, the following vulnerability has been resolved:
net: mana: Use pci_name() for debugfs directory naming
Use pci_name(pdev) for the per-device debugfs directory instead of
hardcoded "0" for PFs and pci_slot_name(pdev->slot) for VFs. The
previous approach had two issues:
1. pci_slot_name() dereferences pdev->slot, which can be NULL for VFs
in environments like generic VFIO passthrough or nested KVM,
causing a NULL pointer dereference.
2. Multiple PFs would all use "0", and VFs across different PCI
domains or buses could share the same slot name, leading to
-EEXIST errors from debugfs_create_dir().
pci_name(pdev) returns the unique BDF address, is always valid, and is
unique across the system.
