      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbridge: br_nd_send: linearize skb before parsing ND options\n\nbr_nd_send() parses neighbour discovery options from ns->opt[] and\nassumes that these options are in the linear part of request.\n\nIts callers only guarantee that the ICMPv6 header and target address\nare available, so the option area can still be non-linear. Parsing\nns->opt[] in that case can access data past the linear buffer.\n\nLinearize request before option parsing and derive ns from the linear\nnetwork header.",
