MediumCVSS 5.5/10Last modified Jun 17, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

Input: sparcspkr - fix refcount leak in bbc_beep_probe

of_find_node_by_path() calls of_find_node_opts_by_path(), which returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.
