"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/v3d: Set DMA segment size to avoid debug warnings\n\nWhen using V3D rendering with CONFIG_DMA_API_DEBUG enabled, the\nkernel occasionally reports a segment size mismatch. This is because\n'max_seg_size' is not set. The kernel defaults to 64K. setting\n'max_seg_size' to the maximum will prevent 'debug_dma_map_sg()'\nfrom complaining about the over-mapping of the V3D segment length.\n\nDMA-API: v3d 1002000000.v3d: mapping sg segment longer than device\n claims to support [len=8290304] [max=65536]\nWARNING: CPU: 0 PID: 493 at kernel/dma/debug.c:1179 debug_dma_map_sg+0x330/0x388\nCPU: 0 UID: 0 PID: 493 Comm: Xorg Not tainted 6.12.53-yocto-standard #1\nHardware name: Raspberry Pi 5 Model B Rev 1.0 (DT)\npstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--)\npc : debug_dma_map_sg+0x330/0x388\nlr : debug_dma_map_sg+0x330/0x388\nsp : ffff8000829a3ac0\nx29: ffff8000829a3ac0 x28: 0000000000000001 x27: ffff8000813fe000\nx26: ffffc1ffc0000000 x25: ffff00010fdeb760 x24: 0000000000000000\nx23: ffff8000816a9bf0 x22: 0000000000000001 x21: 0000000000000002\nx20: 0000000000000002 x19: ffff00010185e810 x18: ffffffffffffffff\nx17: 69766564206e6168 x16: 74207265676e6f6c x15: 20746e656d676573\nx14: 20677320676e6970 x13: 5d34303334393134 x12: 0000000000000000\nx11: 00000000000000c0 x10: 00000000000009c0 x9 : ffff8000800e0b7c\nx8 : ffff00010a315ca0 x7 : ffff8000816a5110 x6 : 0000000000000001\nx5 : 000000000000002b x4 : 0000000000000002 x3 : 0000000000000008\nx2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff00010a315280\nCall trace:\n debug_dma_map_sg+0x330/0x388\n __dma_map_sg_attrs+0xc0/0x278\n dma_map_sgtable+0x30/0x58\n drm_gem_shmem_get_pages_sgt+0xb4/0x140\n v3d_bo_create_finish+0x28/0x130 [v3d]\n v3d_create_bo_ioctl+0x54/0x180 [v3d]\n drm_ioctl_kernel+0xc8/0x140\n drm_ioctl+0x2d4/0x4d8"
