Description

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

scsi: mpi3mr: Fix target device refcount leak in mpi3mr_sas_port_add()

mpi3mr_get_tgtdev_by_addr() increments the target device kref when it returns a device. If a subsequent error triggers a goto out_fail after the tgtdev reference is acquired, the reference is never released because the out_fail path does not call mpi3mr_tgtdev_put(). This prevents the target device structure from ever being freed.

Add a tgtdev put in the out_fail path, guarded by a NULL check since tgtdev is only acquired for SAS_END_DEVICE types and the same cleanup path is shared by earlier error cases where tgtdev is still NULL.
