In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8192-mt6359: Fix error handling in mt8192mt6359devprobe The devicenode pointer is returned by ofparsephandle() with refcount incremented. We should use ofnodeput() on it when done. This function only calls ofnodeput() in the regular path. And it will cause refcount leak in error paths. Fix this by calling ofnodeput() in error handling too.
