  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/mediatek: Disable AFBC support on Mediatek DRM driver  Commit c410fa9b07c3 (\u0022drm/mediatek: Add AFBC support to Mediatek DRM driver\u0022) added AFBC support to Mediatek DRM and enabled the 32x8/split/sparse modifier.  However, this is currently broken on Mediatek MT8188 (Genio 700 EVK platform); tested using upstream Kernel and Mesa (v25.2.1), AFBC is used by default since Mesa v25.0.
