CVE-2022-50109
Linux Kernel Video Driver Reference Count Leak Vulnerability
Description
In the Linux kernel, the following vulnerability has been resolved: video: fbdev: amba-clcd: Fix refcount leak bugs In clcdfb_of_init_display(), we should call of_node_put() for the references returned by of_graph_get_next_endpoint() and of_graph_get_remote_port_parent() which have increased the refcount. Besides, we should call of_node_put() both in fail path or when the references are not used anymore.
