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:
-
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.
-
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.
