  3. CVE-2022-49716
In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3: Fix error handling in gic_populate_ppi_partitions of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. When kcalloc fails, it missing of_node_put() and results in refcount leak. Fix this by goto out_put_node label.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: irqchip/gic-v3: Se ha corregido el error de gestión en gic_populate_ppi_partitions. 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. Cuando kcalloc falla, falta of_node_put() y da como resultado una fuga de refcount. Corrija esto pasando a la etiqueta out_put_node.
