Description OSIDB Bzimport 2025-06-18 12:11:15 UTC 
In the Linux kernel, the following vulnerability has been resolved:

usb: host: ohci-ppc-of: Fix refcount leak bug

In ohci_hcd_ppc_of_probe(), of_find_compatible_node() will return
a node pointer with refcount incremented. We should use of_node_put()
when it is not used anymore.
