In the Linux kernel, the following vulnerability has been resolved: memory: samsung: exynos5422-dmc: Fix refcount leak in of_get_dram_timings of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. This function doesn't call of_node_put() in some error paths. To unify the structure, Add put_node label and goto it on errors.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: memoria: samsung: exynos5422-dmc: Se corrige la fuga de refcount en of_get_dram_timings of_parse_phandle() devuelve un puntero de nodo con refcount incrementado, deberíamos usar of_node_put() en él cuando ya no sea necesario. Esta función no llama a of_node_put() en algunas rutas de error. Para unificar la estructura, agregue la etiqueta put_node y vaya a ella en caso de errores.
