    CVE-2024-42289

    In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: During vport delete send async logout explicitly During vport delete, it is observed that during unload we hit a crash because of stale entries in outstanding command array. For all these stale I/O entries, eh_abort was issued and aborted (fast_fail_io = 2009h) but I/Os could not complete while vport delete is in process of deleting.
