      "title": "net/sched: cls_bpf: prevent unbounded recursion in offload rollback",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: cls_bpf: prevent unbounded recursion in offload rollback\n\nQuan Sun reported [1] a stack overflow in cls_bpf_offload_cmd().\n\nReproducer on netdevsim: add a skip_sw cls_bpf filter, set the\nbpf_tc_accept debugfs knob to 0, then `tc filter replace`. The replace\ncalls tc_setup_cb_replace() which fails. cls_bpf_offload_cmd() then\nswaps prog/oldprog and recursively calls itself to roll back. But\nbpf_tc_accept=0 makes the rollback fail too, which triggers yet another\nrollback frame with the same arguments, and so on until the stack is\nexhausted.\n\nbpf_tc_accept is just a convenient knob for the reproducer. Any driver\nwhose tc_setup_cb_replace() fails twice in a row can hit the same loop,\nso this is not a netdevsim-only issue.\n\nTwo ways to fix it:\n\n  1) Have the rollback call tc_setup_cb_add() on oldprog instead of\n     re-entering cls_bpf_offload_cmd().\n  2) Mark the rollback frame with a flag and skip a second-level\n     rollback from inside it.\n\nGo with (2). It is the smaller change and keeps the original behaviour:\nthe rollback still goes through tc_setup_cb_replace(), so the driver\ngets one real chance to restore its state. If that attempt also fails,\nwe just return the original error instead of recursing.\n\n[1]: https://lore.kernel.org/bpf/ce5a6005-3c5e-4696-9e05-eba9461dc860@std.uestc.edu.cn/T/#u",
