Description OSIDB Bzimport 2025-02-26 03:22:13 UTC 
In the Linux kernel, the following vulnerability has been resolved:

watchdog: ts4800_wdt: Fix refcount leak in ts4800_wdt_probe

of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add  missing of_node_put() in some error paths.
