Linux Kernel Refcount Leak Vulnerability in OHCI NXP USB Driver

A refcount leak vulnerability has been identified in the Linux kernel's OHCI NXP USB driver. The issue arises in the 'ohci_hcd_nxp_probeof_parse_phandle()' function, which returns a node pointer with an incremented reference count. The missing 'of_node_put()' call to decrement the reference count when the node is no longer needed has created a memory leak.

Impact

Exploitation of this vulnerability leads to a memory leak, where reference counts are not properly managed, potentially causing increased memory usage over time.
