Description
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.
