CVE-2026-97409

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

nvme-fc: Do not cancel requests in io target before it is initialized

A new nvme-fc controller in CONNECTING state sees admin request timeout

schedules ctrl->ioerr_work to abort inflight requests. This ends up

calling __nvme_fc_abort_outstanding_ios() which aborts requests in both

admin and io tagsets. In case fc_ctrl->tag_set was not initialized we

see the warning below. This is because ctrl.queue_count is initialized

early in nvme_fc_alloc_ctrl().

nvme nvme0: NVME-FC{0}: starting error recovery Connectivity Loss

INFO: trying to register non-static key.

The code is fine but needs lockdep annotation, or maybe

lpfc 0000:ab:00.0: queue 0 connect admin queue failed (-6).

you didn't initialize this object before use?

turning off the locking correctness validator.

Workqueue: nvme-reset-wq nvme_fc_ctrl_ioerr_work [nvme_fc]
