  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mana: Use pci_name() for debugfs directory naming\n\nUse pci_name(pdev) for the per-device debugfs directory instead of\nhardcoded \"0\" for PFs and pci_slot_name(pdev-\u003eslot) for VFs. The\nprevious approach had two issues:\n\n1. pci_slot_name() dereferences pdev-\u003eslot, which can be NULL for VFs\n   in environments like generic VFIO passthrough or nested KVM,\n   causing a NULL pointer dereference.\n\n2. Multiple PFs would all use \"0\", and VFs across different PCI\n   domains or buses could share the same slot name, leading to\n   -EEXIST errors from debugfs_create_dir().\n\npci_name(pdev) returns the unique BDF address, is always valid, and is\nunique across the system.",
