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.
