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": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/microsoft/mana/gdma_main.c"], "versions": [{"version": "6607c17c6c5e029da03a90085db22daf518232bf", "lessThan": "34dbd7b819544c99c9d96b400fe4db613f40ac4b", "status": "affected", "versionType": "git"}, {"version": "6607c17c6c5e029da03a90085db22daf518232bf", "lessThan": "9211eb97e8f8c28bf9313ab97862d143dbbbef97", "status": "affected", "versionType": "git"}, {"version": "6607c17c6c5e029da03a90085db22daf518232bf", "lessThan": "c116f07ab9d22bb6f355f3cf9e44c1e6a47fe559", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/microsoft/mana/gdma_main.c"], "versions": [{"version": "6.13", "status": "affected"}, {"version": "0", "lessThan": "6.13", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.33", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.10", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.13", "versionEndExcluding": "6.18.33"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.13", "versionEndExcluding": "7.0.10"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.13", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/34dbd7b819544c99c9d96b400fe4db613f40ac4b"}, {"url": "https://git.kernel.org/stable/c/9211eb97e8f8c28bf9313ab97862d143dbbbef97"}, {"url": "https://git.kernel.org/stable/c/c116f07ab9d22bb6f355f3cf9e44c1e6a47fe559"}], "title": "net: mana: Use pci_name() for debugfs directory naming", "x_generator": {"engine": "bippy-1.2.0"}}}}
