In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
scsi: qla2xxx: Initialize NVMe abort_work once at submission<\/p>\n
qla_nvme_fcp_abort() and qla_nvme_ls_abort() ran INIT_WORK() on
\npriv->abort_work immediately before schedule_work(). INIT_WORK()
\nreinitializes the work_struct, resetting its list head and clearing the
\npending bit. If an abort is issued more than once for the same command
\n(for example, concurrent transport teardown and a timeout-driven abort),
\nthe second INIT_WORK() reinitializes a work item that is already queued,
\nwhich can corrupt the workqueue list and lead to crashes or a looping
\nworker.<\/p>\n
Initialize priv->abort_work once at command submission, next to the
\nexisting per-command spin_lock_init(&priv->cmd_lock), and leave only
\nschedule_work() in the abort paths. schedule_work() already does nothing
\nwhen the work item is still pending, so a repeated abort no longer
\ndisturbs an in-flight work item. The command is not returned to the
\ntransport until the final kref_put()\/release callback runs after
\nabort_work has completed, so the work item is idle before priv is reused
\nand the single submission-time INIT_WORK() is safe.<\/p>\n","protected":false},"excerpt":{"rendered":"
