Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
