CVE-2022-49386 Information

Description

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.
