When that happens, it is possible for the adapter\nto be NULL from the first call to idpf_remove(), leading to a NULL\npointer dereference.\n\necho 1 > /sys/class/net/<netif>/device/sriov_numvfs\nreboot\n\nBUG: kernel NULL pointer dereference, address: 0000000000000020\n...\nRIP: 0010:idpf_remove+0x22/0x1f0 [idpf]\n...\n? idpf_remove+0x22/0x1f0 [idpf]\n? idpf_remove+0x1e4/0x1f0 [idpf]\npci_device_remove+0x3f/0xb0\ndevice_release_driver_internal+0x19f/0x200\npci_stop_bus_device+0x6d/0x90\npci_stop_and_remove_bus_device+0x12/0x20\npci_iov_remove_virtfn+0xbe/0x120\nsriov_disable+0x34/0xe0\nidpf_sriov_configure+0x58/0x140 [idpf]\nidpf_remove+0x1b9/0x1f0 [idpf]\nidpf_shutdown+0x12/0x30 [idpf]\npci_device_shutdown+0x35/0x60\ndevice_shutdown+0x156/0x200\n...\n\nReplace the direct idpf_remove() call in idpf_shutdown() with\nidpf_vc_core_deinit() and idpf_deinit_dflt_mbx(), which perform\nthe bulk of the cleanup, such as stopping the init task, freeing IRQs,\ndestroying the vports and freeing the mailbox. This avoids the calls to\nsriov_disable() in addition to a small netdev cleanup, and destroying\nworkqueues, which don't seem to be required on shutdown.","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/4c9106f4906a85f6b13542d862e423bcdc118cc3","https://git.kernel.org/stable/c/79618e952ef4dfa1a17ee0631d5549603fab58d8","https://git.kernel.org/stable/c/88a6d562e92a295648f8636acf2a6aa714241771","https://git.kernel.org/stable/c/9fc9b3dc0d0c189ed205acf1e5fbd73e0becc4d6"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:11.054312287+00:00"},"epss":{"cve":"CVE-2025-22065","score":0.00265,"percentile":0.18456,"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).
