Linux Kernel Refcount Leak Vulnerability in OMAP Display Subsystem

A refcount leak vulnerability has been identified in the Linux kernel's OMAP display subsystem. The issue arises in the 'omapdss_init_fbdev()' function, where 'of_find_node_by_name()' returns a node pointer with an incremented reference count. The vulnerability occurs because the reference count is not properly decremented when the node is no longer needed.

Impact

Exploitation of this vulnerability leads to a refcount leak, which can cause memory management issues such as use-after-free vulnerabilities or memory exhaustion.
