In the Linux kernel, the following vulnerability has been resolved:
drm/stm: Avoid use-after-free issues with crtc and plane
ltdc_load() calls functions drm_crtc_init_with_planes(),
drm_universal_plane_init() and drm_encoder_init(). These functions
should not be called with parameters allocated with devm_kzalloc()
to avoid use-after-free issues [1].
Use allocations managed by the DRM framework.
Found by Linux Verification Center (linuxtesting.org).
