{"id":"CVE-2025-22092","summary":"PCI: Fix NULL dereference in SR-IOV VF creation error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nPCI: Fix NULL dereference in SR-IOV VF creation error path\n\nClean up when virtfn setup fails to prevent NULL pointer dereference\nduring device removal. The kernel oops below occurred due to incorrect\nerror handling flow when pci_setup_device() fails.\n\nAdd pci_iov_scan_device(), which handles virtfn allocation and setup and\ncleans up if pci_setup_device() fails, so pci_iov_add_virtfn() doesn't need\nto call pci_stop_and_remove_bus_device().  This prevents accessing\npartially initialized virtfn devices during removal.\n\n  BUG: kernel NULL pointer dereference, address: 00000000000000d0\n  RIP: 0010:device_del+0x3d/0x3d0\n  Call Trace:\n   pci_remove_bus_device+0x7c/0x100\n   pci_iov_add_virtfn+0xfa/0x200\n   sriov_enable+0x208/0x420\n   mlx5_core_sriov_configure+0x6a/0x160 [mlx5_core]\n   sriov_numvfs_store+0xae/0x1a0\n\n[bhelgaas: commit log, return ERR_PTR(-ENOMEM) directly]","modified":"2026-04-02T12:45:21.225705Z","published":"2025-04-16T14:12:43.879Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22092.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/04d50d953ab46d96b0b32d5ad955fceaa28622db"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c67a233834b778b8c78f8b62c072ccf87a9eb6d0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ef421b4d206f0d3681804b8f94f06a8458a53aaf"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22092.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-22092"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e3f30d563a388220a7c4e3b9a7b52ac0b0324b26"},{"fixed":"ef421b4d206f0d3681804b8f94f06a8458a53aaf"},{"fixed":"c67a233834b778b8c78f8b62c072ccf87a9eb6d0"},{"fixed":"04d50d953ab46d96b0b32d5ad955fceaa28622db"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-22092.json"}}],"schema_version":"1.7.5"}
