Description OSIDB Bzimport 2025-06-18 12:05:14 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/meson: Fix refcount bugs in meson_vpu_has_available_connectors()

In this function, there are two refcount leak bugs:
(1) when breaking out of for_each_endpoint_of_node(), we need call
the of_node_put() for the 'ep';
(2) we should call of_node_put() for the reference returned by
of_graph_get_remote_port() when it is not used anymore.
