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 kref_put()/release callback runs after
abort_work has completed, so the work item is idle before priv is reused
and the single submission-time INIT_WORK() is safe.
