      "title": "tipc: reject inverted service ranges from peer bindings",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ntipc: reject inverted service ranges from peer bindings\n\ntipc_update_nametbl() inserts a binding advertised by a peer node using\nthe lower and upper service-range bounds taken directly from the wire,\nwithout checking that lower <= upper. The local bind path validates the\nordering (tipc_uaddr_valid()), but the name-distribution path does not.\n\nA binding with lower > upper is inserted at the far end of the\nservice-range rbtree (keyed on lower) where no lookup or withdrawal can\never match it (service_range_foreach_match() requires sr->lower <= end).\nThe publication, its service_range node and the augmented rbtree entry\nare then leaked for the lifetime of the namespace, and there is no\nper-peer cap equivalent to TIPC_MAX_PUBL on locally created bindings.\n\nReject inverted ranges in the network path as well. A peer node can\notherwise leak unbounded binding-table memory by sending PUBLICATION\nitems with lower > upper.",
