  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/mxsfb: Disable overlay plane in mxsfb_plane_overlay_atomic_disable()\n\nWhen disabling overlay plane in mxsfb_plane_overlay_atomic_update(),\noverlay plane's framebuffer pointer is NULL.  So, dereferencing it would\ncause a kernel Oops(NULL pointer dereferencing).  Fix the issue by\ndisabling overlay plane in mxsfb_plane_overlay_atomic_disable() instead.",
