In the Linux kernel, the following vulnerability has been resolved:

drm/v3d: Set DMA segment size to avoid debug warnings

When using V3D rendering with CONFIG_DMA_API_DEBUG enabled, the kernel occasionally reports a segment size mismatch. This is because 'max_seg_size' is not set. The kernel defaults to 64K. setting 'max_seg_size' to the maximum will prevent 'debug_dma_map_sg()' from complaining about the over-mapping of the V3D segment length.
