## Overview

A flaw was found in the Linux kernel's remoteproc SCP component. This vulnerability involves a device reference leak, where the system fails to properly release a reference to a device during a driver data lookup. This occurs specifically before the driver has been fully bound. A local attacker could potentially exploit this issue to cause resource exhaustion, leading to a Denial of Service (DoS) condition.
