Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A regression in the removal of procfs host directories has been fixed in the Linux kernel. The issue is related to the scsi proc hostdir rm() function, which decreases a reference counter and must only be called once per host that is removed. This change does not require modifications to scsi add host with dma() as it will return 0 (success) if scsi proc host add() is called.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
