Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-11 21:31

Details

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.

Severity ?

5.5 (Medium)
