In the Linux kernel, the following vulnerability has been resolved: ARM: exynos: Fix refcount leak in exynos_map_pmu of_find_matching_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak. of_node_put() checks null pointer.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ARM: exynos: Se corrige la fuga de refcount en exynos_map_pmu of_find_matching_node() devuelve un puntero de nodo con refcount incrementado, deberíamos usar of_node_put() en él cuando ya no lo necesitemos. Agregue of_node_put() faltante para evitar la fuga de refcount. of_node_put() verifica el puntero nulo.
