High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: mmc: loongson2: Fix sg iteration in data reorder functions In ls2k0500_mmc_reorder_cmd_data() and ls2k2000_mmc_reorder_cmd_data(), the for_each_sg() macro already iterates over the scatterlist entries, with 'sg' pointing to the current entry. However, the code incorrectly uses '&sg[i]' and 'sg_dma_len(&sg[i])' inside the loop, which treats 'sg' as an array base and indexes it again, leading to access of wrong sg entries (or out-of-bounds if the list is not an array).
