      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf, xdp: move offload check into dev_xdp_install()\n\nbpf_xdp_link_update() calls dev_xdp_install() directly and skips\ndev_xdp_attach(), so the checks in dev_xdp_attach() do not run. A user can\nmake an XDP link with a normal program and then swap in an offloaded or\ndevice-bound program with BPF_LINK_UPDATE, which puts it on the software\npath.\n\ndev_xdp_install() is the one place all three paths go through:\n\"ip link set xdp\" and BPF_LINK_CREATE reach it via dev_xdp_attach(), and\nBPF_LINK_UPDATE calls it directly. So move the program checks (offloaded,\nbound to another device, device-bound in generic mode, native vs generic,\nDEVMAP and CPUMAP) there, and keep only the netlink-flag check\n(XDP_FLAGS_UPDATE_IF_NOEXIST) in dev_xdp_attach().",
