PublishedIn the Linux kernel, the following vulnerability has been resolved: crypto: mxs-dcp - fix source scatterlist length access mxs_dcp_aes_block_crypt() uses sg_dma_len() without mapping the source scatterlist with dma_map_sg() first. Therefore, sg_dma_len() is invalid and could return zero or a stale DMA length, causing encryption and decryption to process the wrong number of bytes when CONFIG_NEED_SG_DMA_LENGTH=y. Use the original scatterlist length instead.
