Local denial of service via leaked display modes
Published Feb 26, 2025 · Updated May 11, 2026
A memory leak in the Linux kernel DRM i.MX parallel-display driver allows local users to exhaust memory through failed display-mode queries. imx_pd_connector_get_modes allocates a drm_display_mode object but returns after of_get_drm_display_mode fails without calling drm_mode_destroy on that object. Local low-privileged access and the relevant i.MX display path are required; repeated failures can deplete kernel memory and interrupt service.
