CVE-2026-43192
dm mpath: Add missing dm_put_device when failing to get scsi dh name
Description
In the Linux kernel, the following vulnerability has been resolved: dm mpath: Add missing dm_put_device when failing to get scsi dh name When commit fd81bc5cca8f ("scsi: device_handler: Return error pointer in scsi_dh_attached_handler_name()") added code to fail parsing the path if scsi_dh_attached_handler_name() failed with -ENOMEM, it didn't clean up the reference to the path device that had just been taken. Fix this, and steamline the error paths of parse_path() a little.
