In the Linux kernel, the following vulnerability has been resolved: Revert "mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4K" The commit 8396c793ffdf ("mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4K") increased the max_req_size, even for 4K pages, causing various issues: - Panic booting the kernel/rootfs from an SD card on Rockchip RK3566 - Panic booting the kernel/rootfs from an SD card on StarFive JH7100 - "swiotlb buffer is full" and data corruption on StarFive JH7110 At this stage no fix have been found, so it's probably better to just revert the change.
