      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrop_monitor: fix out-of-bounds write in reset_per_cpu_data()\n\nIn reset_per_cpu_data(), al is computed as:\n\n    al = sizeof(struct net_dm_alert_msg);\n    al += dm_hit_limit * sizeof(struct net_dm_drop_point);\n    al += sizeof(struct nlattr);\n\n    skb = genlmsg_new(al, GFP_KERNEL);\n    ...\n    nla = nla_reserve(skb, NLA_UNSPEC, sizeof(struct net_dm_alert_msg));\n    ...\n    msg = nla_data(nla);\n    memset(msg, 0, al);\n\nBecause al includes sizeof(struct nlattr) (the 4-byte attribute header),\ngenlmsg_new() allocates al bytes of tailroom starting at nla.\nHowever, msg points to nla_data(nla), which is located\nsizeof(struct nlattr) bytes past nla. Calling memset(msg, 0, al)\ntherefore writes al bytes starting from msg, exceeding the allocated\nbuffer by sizeof(struct nlattr) (4 bytes) and corrupting\nskb_shared_info.\n\nFix this by letting al represent only the payload length, allocating\nthe skb with genlmsg_new(nla_total_size(al), GFP_KERNEL), and zeroing\nal bytes from msg.",
