"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mvpp2: sync RX data at the hardware packet offset\n\nmvpp2 programs the RX queue packet offset, so hardware writes received\ndata at dma_addr + MVPP2_SKB_HEADROOM. The current CPU sync starts at\ndma_addr and only covers rx_bytes + MVPP2_MH_SIZE bytes, which syncs the\nunused headroom and misses the same number of bytes at the packet tail.\n\nOn non-coherent DMA systems this can leave the CPU reading stale cache\ncontents for the end of the received frame.\n\nUse dma_sync_single_range_for_cpu() with MVPP2_SKB_HEADROOM as the range\noffset so the sync covers the Marvell header and packet data actually\nwritten by hardware."

"value": "AV:N - The vulnerable code is in the Ethernet RX path and is reached by packets received on an affected mvpp2 network interface. A remote peer can trigger it by sending network traffic to a system using this driver.\nAC:L - On affected non-coherent DMA deployments, exploitation only requires sending received frames that traverse the normal RX/NAPI path. There is no race or attacker-uncontrolled timing requirement in the vulnerable path.\nPR:N - No local privileges or authentication are required to reach the receive path. The attacker only needs network reachability to the affected interface.\nUI:N - Packet reception and processing happen automatically once the interface is up. No user action is required.\nS:U - The bug affects packet data handled within the same kernel/network-device security authority. It does not cross a VM, IOMMU, or other separate security boundary.\nC:H - The incorrect DMA sync can leave stale cache contents in the tail of received skbs, potentially exposing previous packet-buffer contents through delivery, forwarding, or reflection. Repeated remote triggering can disclose more than a few bounded bytes of network data over time.\nI:L - The CPU-visible packet tail can differ from the actual frame written by hardware, corrupting data delivered to XDP, the network stack, or applications. This is packet/data integrity loss, but not an arbitrary kernel memory write or control-flow primitive.\nA:L - An attacker can repeatedly cause corrupted received packets, leading to packet drops, protocol failures, or degraded network service. The investigated path does not indicate a kernel panic, hang, or reliable full-system DoS."
