      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmmc: loongson2: Fix sg iteration in data reorder functions\n\nIn ls2k0500_mmc_reorder_cmd_data() and ls2k2000_mmc_reorder_cmd_data(),\nthe for_each_sg() macro already iterates over the scatterlist entries,\nwith 'sg' pointing to the current entry. However, the code incorrectly\nuses '&sg[i]' and 'sg_dma_len(&sg[i])' inside the loop, which treats\n'sg' as an array base and indexes it again, leading to access of\nwrong sg entries (or out-of-bounds if the list is not an array).",
