Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: drm/mcde: Fix refcount leak in mcde_dsi_bind Every iteration of for_each_available_child_of_node() decrements the reference counter of the previous node. There is no decrement when break out from the loop and results in refcount leak. Add missing of_node_put() to fix this.

Cada iteración de for_each_available_child_of_node() decrementa el contador de referencias del nodo anterior. No se produce decremento al salir del bucle, lo que provoca una fuga de recuento de referencias. Para solucionar esto, se ha añadido la función of_node_put() (faltante)."
