  3. CVE-2022-50194
In the Linux kernel, the following vulnerability has been resolved: soc: qcom: aoss: Fix refcount leak in qmp_cooling_devices_register 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 child node. Add missing of_node_put() to avoid refcount leak.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: soc: qcom: aoss: Se corrige la fuga de recuento de referencias en qmp_cooling_devices_register. Cada iteración de for_each_available_child_of_node() disminuye el recuento de referencias del nodo anterior. Al interrumpir un bucle for_each_available_child_of_node() antes de tiempo, debemos llamar explícitamente a of_node_put() en el nodo secundario. Añada la función of_node_put() que falta para evitar la fuga de recuento de referencias.
