Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ARM: meson: Se corrige la pérdida de recuento de referencias en meson_smp_prepare_cpus of_find_compatible_node() devuelve un puntero de nodo con el recuento de referencias incrementado; cuando termine, debemos usar of_node_put() en él. Agregue el error of_node_put() faltante para evitar la pérdida de recuento de referencias.
