Description OSIDB Bzimport 2025-04-01 16:02:18 UTC 
In the Linux kernel, the following vulnerability has been resolved:

rapidio: fix an API misues when rio_add_net() fails

rio_add_net() calls device_register() and fails when device_register()
fails.  Thus, put_device() should be used rather than kfree().  Add
"mport->net = NULL;" to avoid a use after free issue.
