memory_map 在 Linux 中没有给出预期的结果

Question

Linux 系统上的查询 .all memory_map 给出了意想不到的结果，因为所有属性的起始内存位置 = 0x00000000 以及结束内存位置 = 0x00000000。是不是觉得很奇怪？

操作系统： Kali Linux

osquery 版本： 4.0.2（当前）

我已尝试在osquery/issues/ 上搜索问题

代码在 CLI 上的准确复制是：

osqueryi
.all memory_map

与以下结果相同：

osqueryi
SELECT * FROM memory_map

osqueryi 的输出只是一条消息，表明它正在使用虚拟数据库，如下所示。

Using a virtual database. Need help, type '.help'

而.all memory_map的输出如下：

Answer 1

memory_map 表需要 root 权限。你是用root来测试的吗？

（如果我不使用提升的权限运行，我可以复制它）

Answer 2

更新：是的，我使用的是 root 用户。我最终将我的系统更改为 Kubuntu 19.04，它就像一个魅力。
