In the Linux kernel, the following vulnerability has been resolved:mtk-sd: Prevent memory corruption from DMA map failureIf msdc_prepare_data() fails to map the DMA region, the request isnot prepared for data receiving, but msdc_start_data() proceedsthe DMA with previous setting.Since this will lead a memory corruption, we have to stop therequest operation soon after the msdc_prepare_data() fails toprepare it.
