Description OSIDB Bzimport 2026-05-27 15:05:07 UTC
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.
