In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ti: am65-cpsw-nuss: Fix some refcount leaks of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. am65_cpsw_init_cpts() and am65_cpsw_nuss_probe() don't release the refcount in error case. Add missing of_node_put() to avoid refcount leak.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: ethernet: ti: am65-cpsw-nuss: Se corrigen algunas fugas de refcount of_get_child_by_name() devuelve un puntero de nodo con refcount incrementado, deberíamos usar of_node_put() en él cuando ya no lo necesitemos. am65_cpsw_init_cpts() y am65_cpsw_nuss_probe() no liberan el refcount en caso de error. Agregue of_node_put() faltante para evitar la fuga de refcount.
