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.","categories":["Operating
