In the Linux kernel, the following vulnerability has been resolved: nvmet: avoid recursive nvmet-wq flush in nvmet_ctrl_free nvmet_tcp_release_queue_work() runs on nvmet-wq and can drop the final controller reference through nvmet_cq_put(). If that triggers nvmet_ctrl_free(), the teardown path flushes ctrl->async_event_work on the same nvmet-wq. Call chain: nvmet_tcp_schedule_release_queue() kref_put(&queue->kref, nvmet_tcp_release_queue) nvmet_tcp_release_queue() queue_work(nvmet_wq, &queue->release_work) <--- nvmet_wq process_one_work() nvmet_tcp_release_queue_work() nvmet_cq_put(&queue->nvme_cq) nvmet_cq_destroy() nvmet_ctrl_put(cq->ctrl) nvmet_ctrl_free() flush_work(&ctrl->async_event_work) <--- nvmet_wq Previously Scheduled by :- nvmet_add_async_event queue_work(nvmet_wq, &ctrl->async_event_work); This trips lockdep with a possible recursive locking warning.

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

    drbd: Balance RCU calls in drbd_adm_dump_devices() (CVE-2026-53128)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - nvmet: avoid recursive nvmet-wq flush in nvmet_ctrl_free nvmet_tcp_release_queue_work() runs on nvmet-wq     and can drop the final controller reference through nvmet_cq_put(). If that triggers nvmet_ctrl_free(),     the teardown path flushes ctrl->async_event_work on the same nvmet-wq. Call chain:
    nvmet_tcp_schedule_release_queue() kref_put(&queue->kref, nvmet_tcp_release_queue)     nvmet_tcp_release_queue() queue_work(nvmet_wq, &queue->release_work) <--- nvmet_wq process_one_work()     nvmet_tcp_release_queue_work() nvmet_cq_put(&queue->nvme_cq) nvmet_cq_destroy() nvmet_ctrl_put(cq->ctrl)     nvmet_ctrl_free() flush_work(&ctrl->async_event_work) <--- nvmet_wq Previously Scheduled by :-     nvmet_add_async_event queue_work(nvmet_wq, &ctrl->async_event_work); This trips lockdep with a possible     recursive locking warning.
