Description OSIDB Bzimport 2025-02-26 03:02:55 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: dsa: microchip: ksz_common: Fix refcount leak bug

In ksz_switch_register(), we should call of_node_put() for the
reference returned by of_get_child_by_name() which has increased
the refcount.
