Title
net: ena: Add validation for completion descriptors consistency
Summary
In the Linux kernel, the following vulnerability has been resolved: net: ena: Add validation for completion descriptors consistency Validate that `first` flag is set only for the first descriptor in multi-buffer packets. In case of an invalid descriptor, a reset will occur. A new reset reason for RX data corruption has been added.

ENA is the standard NIC on internet-facing AWS EC2 instances, so the path is driven by remote, unauthenticated traffic.\nAC:L - No specific memory layout, victim state, or non-default configuration is required; the descriptor-framing path is exercised by ordinary multi-buffer RX traffic and the driver\u0027s cross-poll partial-packet state can be driven by sustained large-packet load. Per the rule to choose the higher severity when uncertain, the influenceable device-side framing condition is scored as Low rather than High.\nPR:N - Processing happens in NAPI/softirq context before any socket, filesystem, or authentication layer is reached, so no account or capability on the target is needed. A remote peer simply sends packets to the interface.\nUI:N - The RX completion path runs automatically whenever the interface is up and receiving traffic. No victim action of any kind is required.\nS:U - The mis-framed descriptors corrupt driver state and skb contents within the same kernel/host security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Merged descriptor chains splice RX buffers belonging to unrelated packets into a single skb delivered to the network stack, and the accumulated `buf_offset`/`buf_len` can describe fragments extending past the real allocation, giving out-of-bounds reads. Stale page pointers reaching `skb_add_rx_frag()` constitute a use-after-free, which is scored High for confidentiality.\nI:H - The unguarded fragment loop can `page_ref_inc()` and `skb_add_rx_frag()` a stale or already-released page and DMA-unmap an already-unmapped buffer, producing double-free/UAF heap-corruption primitives; corrupted packet data is also injected into the stack. Memory corruption of this kind is exploitable for control-flow hijack and is scored High.\nA:H - A NULL `rx_info-\u003epage` reaching `page_ref_inc()`/`skb_add_rx_frag()` is an immediate kernel oops, and even the benign outcome is RX ring desync that stalls buffer replenishment and forces a full device reset, dropping network connectivity. Any kernel crash or hang is scored High."
