CVE-2023-53864

*** Pendiente de traducción *** 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&amp;#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.
