The\nprevious approach had two issues:\n\n1. pci_slot_name() dereferences pdev->slot, 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-476"],"references":["https://git.kernel.org/stable/c/34dbd7b819544c99c9d96b400fe4db613f40ac4b","https://git.kernel.org/stable/c/9211eb97e8f8c28bf9313ab97862d143dbbbef97","https://git.kernel.org/stable/c/c116f07ab9d22bb6f355f3cf9e44c1e6a47fe559"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-53324","score":0.0016,"percentile":0.05154,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
