CVE-2023-53324

Local service interruption via leaked plane-state references

Published Sep 16, 2025 · Updated Sep 16, 2025

Resource leak in the Linux kernel MSM MDP5 display driver allows local users to exhaust memory and interrupt service. The mdp5_plane_reset function manually frees the prior plane state instead of calling __drm_atomic_helper_plane_destroy_state, so the plane_state->commit reference is not released. Reachability requires local low-privileged access and the MSM MDP5 display driver; repeated state resets consume kernel memory until service interruption.
