Linux Kernel Refcount Leak Vulnerability in SCMI Regulator

A refcount leak vulnerability has been identified in the Linux kernel's SCMI regulator implementation. The issue arises because the function 'of_find_node_by_name()' returns a node pointer with an incremented reference count, which is not properly decremented after use. This oversight can lead to a memory management issue, where the reference count does not accurately reflect the actual usage, potentially causing resource leaks.

Impact

Exploitation of this vulnerability leads to a refcount leak, where the reference count of a node is not properly managed, potentially causing memory management issues.
