Description
In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-tdes - fix DMA sync direction Before DMA output is consumed by the CPU, ->dma_addr_out must be synced with dma_sync_single_for_cpu() instead of dma_sync_single_for_device(). Using the wrong direction can return stale cache data on non-coherent platforms.
