In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3: Fix refcount leak in gic_populate_ppi_partitions of_find_node_by_phandle() 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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: irqchip/gic-v3: Se corrige la pérdida de recuento de referencias en gic_populate_ppi_partitions. of_find_node_by_phandle() devuelve un puntero de nodo con el recuento de referencias incrementado. Deberíamos usar of_node_put() en él cuando ya no lo necesitemos. Se agrega el error of_node_put() faltante para evitar la pérdida de recuento de referencias.
