Description OSIDB Bzimport 2026-09-16 12:53:16 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: v4l2-fwnode: Fix fwnode leak in v4l2_fwnode_parse_link

In v4l2_fwnode_parse_link(), the remote endpoint fwnode reference is
acquired using fwnode_graph_get_remote_endpoint(). This reference is
properly released in the error paths, but it is leaked on the success
path.

Add the missing fwnode_handle_put() before returning 0 to prevent the
reference leak.

[Sakari Ailus: Fix subject prefix and coding style a little.]
