CVE-2026-80748 is fixed in linux on 1 platform by DEBIAN-CVE-2026-80748 (version 7.1.10-1), released September 4, 2026. It is not reported as exploited. Patch Radar priority: High.
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).
