Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: mvpp2: sync RX data at the hardware packet offset<br /> <br /> mvpp2 programs the RX queue packet offset, so hardware writes received<br /> data at dma_addr + MVPP2_SKB_HEADROOM. The current CPU sync starts at<br /> dma_addr and only covers rx_bytes + MVPP2_MH_SIZE bytes, which syncs the<br /> unused headroom and misses the same number of bytes at the packet tail.<br /> <br /> On non-coherent DMA systems this can leave the CPU reading stale cache<br /> contents for the end of the received frame.<br /> <br /> Use dma_sync_single_range_for_cpu() with MVPP2_SKB_HEADROOM as the range<br /> offset so the sync covers the Marvell header and packet data actually<br /> written by hardware.
