      "title": "bpf: Reject fragmented frames in devmap",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Reject fragmented frames in devmap\n\nDevmap broadcast redirects clone the packet for all but the last\ndestination.\n\nFor native XDP, that clone path copies only the linear xdp_frame data,\nwhile fragmented frames keep skb_shared_info in tailroom outside the\nlinear area. Cloning such a frame leaves XDP_FLAGS_HAS_FRAGS set but\nwithout valid frag metadata, and the later free path can interpret\nuninitialized tail data as skb_shared_info, leading to an out-of-bounds\naccess during frame return.\n\nReject fragmented native XDP frames in dev_map_enqueue_clone().\n\nAdd the same restriction to the generic XDP clone path in\ndev_map_redirect_clone(). Generic XDP represents fragmented packets as\nnonlinear skbs, and rejecting them here keeps clone-based broadcast\nsupport aligned between native and generic XDP.",
