Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/mxsfb: Disable overlay plane in mxsfb_plane_overlay_atomic_disable()<br />
<br />
When disabling overlay plane in mxsfb_plane_overlay_atomic_update(),<br />
overlay plane&#39;s framebuffer pointer is NULL. So, dereferencing it would<br />
cause a kernel Oops(NULL pointer dereferencing). Fix the issue by<br />
disabling overlay plane in mxsfb_plane_overlay_atomic_disable() instead.
