CVE-2023-53864

CVE-2023-53864 affects the Linux kernel DRM/MXSFB path. The issue could lead to a kernel Oops from NULL pointer dereference when disabling the overlay plane during mxsfb_plane_overlay_atomic_update(), because the overlay plane framebuffer pointer could be NULL. The fix disables the overlay plane ...
