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.
A flaw was found in the Linux kernel's device-mapper multipath (dm mpath) subsystem. A missing cleanup operation occurs when the system fails to retrieve a SCSI device handler name due to memory allocation issues. This oversight can lead to a resource leak, where references to path devices are not properly released. Over time, this resource exhaustion could allow a local attacker to cause a Denial of Service (DoS) by making the system unresponsive.
