## Overview

In the Linux kernel, the following vulnerability has been resolved:

scsi: core: Fix a procfs host directory removal regression

scsi_proc_hostdir_rm() decreases a reference counter and hence must only be
called once per host that is removed. This change does not require a
scsi_add_host_with_dma() change since scsi_add_host_with_dma() will return
0 (success) if scsi_proc_host_add() is called.
