This results multiple WARNings from sysfs_remove_group() as\nthe controller rport device attributes are removed too early.\n\nReplace the fcoe_port's destroy_work queue. It's not needed.\n\nThe problem is easily reproducible with the following steps.\n\nExample:\n\n  $ dmesg -w &\n  $ systemctl enable --now fcoe\n  $ fipvlan -s -c ens2f1\n  $ fcoeadm -d ens2f1.802\n  [  583.464488] host2: libfc: Link down on port (7500a1)\n  [  583.472651] bnx2fc: 7500a1 - rport not created Yet!!\n  [  583.490468] ------------[ cut here ]------------\n  [  583.538725] sysfs group 'power' not found for kobject 'rport-2:0-0'\n  [  583.568814] WARNING: CPU: 3 PID: 192 at fs/sysfs/group.c:279 sysfs_remove_group+0x6f/0x80\n  [  583.607130] Modules linked in: dm_service_time 8021q garp mrp stp llc bnx2fc cnic uio rpcsec_gss_krb5 auth_rpcgss nfsv4 ...\n  [  583.942994] CPU: 3 PID: 192 Comm: kworker/3:2 Kdump: loaded Not tainted 5.14.0-39.el9.x86_64 #1\n  [  583.984105] Hardware name: HP ProLiant DL120 G7, BIOS J01 07/01/2013\n  [  584.016535] Workqueue: fc_wq_2 fc_rport_final_delete [scsi_transport_fc]\n  [  584.050691] RIP: 0010:sysfs_remove_group+0x6f/0x80\n  [  584.074725] Code: ff 5b 48 89 ef 5d 41 5c e9 ee c0 ff ff 48 89 ef e8 f6 b8 ff ff eb d1 49 8b 14 24 48 8b 33 48 c7 c7 ...\n  [  584.162586] RSP: 0018:ffffb567c15afdc0 EFLAGS: 00010282\n  [  584.188225] RAX: 0000000000000000 RBX: ffffffff8eec4220 RCX: 0000000000000000\n  [  584.221053] RDX: ffff8c1586ce84c0 RSI: ffff8c1586cd7cc0 RDI: ffff8c1586cd7cc0\n  [  584.255089] RBP: 0000000000000000 R08: 0000000000000000 R09: ffffb567c15afc00\n  [  584.287954] R10: ffffb567c15afbf8 R11: ffffffff8fbe7f28 R12: ffff8c1486326400\n  [  584.322356] R13: ffff8c1486326480 R14: ffff8c1483a4a000 R15: 0000000000000004\n  [  584.355379] FS:  0000000000000000(0000) GS:ffff8c1586cc0000(0000) knlGS:0000000000000000\n  [  584.394419] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n  [  584.421123] CR2: 00007fe95a6f7840 CR3: 0000000107674002 CR4: 00000000000606e0\n  [  584.454888] Call Trace:\n  [  584.466108]  device_del+0xb2/0x3e0\n  [  584.481701]  device_unregister+0x13/0x60\n  [  584.501306]  bsg_unregister_queue+0x5b/0x80\n  [  584.522029]  bsg_remove_queue+0x1c/0x40\n  [  584.541884]  fc_rport_final_delete+0xf3/0x1d0 [scsi_transport_fc]\n  [  584.573823]  process_one_work+0x1e3/0x3b0\n  [  584.592396]  worker_thread+0x50/0x3b0\n  [  584.609256]  ? rescuer_thread+0x370/0x370\n  [  584.628877]  kthread+0x149/0x170\n  [  584.643673]  ? set_kthread_struct+0x40/0x40\n  [  584.662909]  ret_from_fork+0x22/0x30\n  [  584.680002] ---[ end trace 53575ecefa942ece ]---","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":[],"references":["https://git.kernel.org/stable/c/00849de10f798a9538242824a51b1756e7110754","https://git.kernel.org/stable/c/262550f29c750f7876b6ed1244281e72b64ebffb","https://git.kernel.org/stable/c/2a12fe8248a38437b95b942bbe85aced72e6e2eb","https://git.kernel.org/stable/c/847f9ea4c5186fdb7b84297e3eeed9e340e83fce","https://git.kernel.org/stable/c/ace7b6ef41251c5fe47f629a9a922382fb7b0a6b"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:52:00.836172422+00:00"},"epss":{"cve":"CVE-2022-48758","score":0.00215,"percentile":0.11975,"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).
