CVE-2024-40932

Kernel memory exhaustion via leaked duplicated EDID

Published Jul 12, 2024 · Updated May 11, 2026

Memory leak in the Linux Exynos VIDI DRM driver allows local users to exhaust kernel memory through repeated connector mode queries. The vidi_get_modes function duplicates user-supplied EDID data, passes it to drm_add_edid_modes, and returns without freeing the allocation. Exploitation requires low-privileged local access to the VIDI DRM interface on a system using the Exynos virtual display driver, and repeated queries can interrupt service.
