How to fix?

There is no fixed version for Centos:10 kernel-rt-debug.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug package and not the kernel-rt-debug package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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.]
