In the Linux kernel, the following vulnerability has been resolved:
scsi: core: Fix a procfs host directory removal regression
scsiprochostdirrm() decreases a reference counter and hence must only be called once per host that is removed. This change does not require a scsiaddhostwithdma() change since scsiaddhostwithdma() will return 0 (success) if scsiprochostadd() is called.
