CVE-2023-53385

Service interruption via unreleased device references

Published Sep 18, 2025 · Updated Sep 18, 2025

A resource leak in the Linux kernel MDP3 media driver allows local users to interrupt service by exhausting device references. In mtk-mdp3-comp.c, MDP3 component setup obtains platform-device references through of_find_device_by_node but omits the matching put_device releases. Reachability requires low-privileged local access and the affected MediaTek MDP3 driver; the published consequence is availability loss from resource exhaustion.
