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