  3. CVE-2022-49346
In the Linux kernel, the following vulnerability has been resolved: net: dsa: lantiq_gswip: Fix refcount leak in gswip_gphy_fw_list Every iteration of for_each_available_child_of_node() decrements the reference count of the previous node. when breaking early from a for_each_available_child_of_node() loop, we need to explicitly call of_node_put() on the gphy_fw_np. Add missing of_node_put() to avoid refcount leak.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: dsa: lantiq_gswip: Se corrige la pérdida de recuento de referencias en gswip_gphy_fw_list Cada iteración de for_each_available_child_of_node() disminuye el recuento de referencias del nodo anterior. Al salir antes de un bucle for_each_available_child_of_node(), debemos llamar explícitamente a of_node_put() en gphy_fw_np. Agregue of_node_put() faltante para evitar la pérdida de recuento de referencias.
