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.","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6607c17c6c5e029da03a90085db22daf518232bf"},{"fixed":"34dbd7b819544c99c9d96b400fe4db613f40ac4b"},{"fixed":"9211eb97e8f8c28bf9313ab97862d143dbbbef97"},{"fixed":"c116f07ab9d22bb6f355f3cf9e44c1e6a47fe559"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53324.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53324.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/34dbd7b819544c99c9d96b400fe4db613f40ac4b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9211eb97e8f8c28bf9313ab97862d143dbbbef97"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c116f07ab9d22bb6f355f3cf9e44c1e6a47fe559"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53324.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53324"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53324.json"}}
