What it is

In the Linux kernel, the following vulnerability has been resolved:

drm/mxsfb: Disable overlay plane in mxsfb_plane_overlay_atomic_disable()

When disabling overlay plane in mxsfb_plane_overlay_atomic_update(),

overlay plane's framebuffer pointer is NULL. So, dereferencing it would

cause a kernel Oops(NULL pointer dereferencing). Fix the issue by

disabling overlay plane in mxsfb_plane_overlay_atomic_disable() instead.
