Description OSIDB Bzimport 2025-02-26 03:12:26 UTC 
In the Linux kernel, the following vulnerability has been resolved:

xtensa: xtfpga: Fix refcount leak bug in setup

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