NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-core package and not the kernel-debug-core package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
