  3. CVE-2022-49714
In the Linux kernel, the following vulnerability has been resolved: irqchip/realtek-rtl: Fix refcount leak in map_interrupts of_find_node_by_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. This function doesn't call of_node_put() in error path. Call of_node_put() directly after of_property_read_u32() to cover both normal path and error path.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: irqchip/realtek-rtl: Se ha corregido la pérdida de refcount en map_interrupts of_find_node_by_phandle() devuelve un puntero de nodo con refcount incrementado, deberíamos usar of_node_put() en él cuando ya no sea necesario. Esta función no llama a of_node_put() en la ruta de error. Llame a of_node_put() directamente después de of_property_read_u32() para cubrir tanto la ruta normal como la ruta de error.
