Linux Kernel Refcount Leak Vulnerability in IMX SC Thermal Driver

A refcount leak vulnerability has been identified in the Linux kernel's IMX SC thermal driver. 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 of a node is not correctly managed, potentially causing resource leaks.

Impact

Exploitation of this vulnerability leads to a refcount leak, where reference counts are not properly decremented, causing potential memory management issues.
