CVE-2026-89860

/// Technical description

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

scsi: qla2xxx: Initialize NVMe abort_work once at submission

qla_nvme_fcp_abort() and qla_nvme_ls_abort() ran INIT_WORK() on

priv->abort_work immediately before schedule_work(). INIT_WORK()

reinitializes the work_struct, resetting its list head and clearing the

pending bit. If an abort is issued more than once for the same command

(for example, concurrent transport teardown and a timeout-driven abort),

the second INIT_WORK() reinitializes a work item that is already queued,

which can corrupt the workqueue list and lead to crashes or a looping

worker.

Initialize priv->abort_work once at command submission, next to the

existing per-command spin_lock_init(&priv->cmd_lock), and leave only

schedule_work() in the abort paths. schedule_work() already does nothing

when the work item is still pending, so a repeated abort no longer

disturbs an in-flight work item. The command is not returned to the

transport until the final k

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
