Description OSIDB Bzimport 2025-02-26 03:05:59 UTC
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.
