buffer memory space的意思|示意

Memory space breach — Accomplished via stack overflow, buffer overrun, or heap error, enables execution of arbitrary code supplied by the attacker with the permissions of the host process.

内存空间缺口——通过栈溢出、缓冲区溢出或堆错误来实现，以宿主进程的权限执行攻击者提供的任何代码。

Furthermore, compressed pages of a DB2 table space remain compressed in the DB2 buffer pool in main memory.

而且DB 2表空间的压缩页在主内存的db2缓冲池中仍保持压缩。

There might not be enough disk space to complete the file write operation, or allocating the buffer could fail if not enough memory is available.

可能没有足够的磁盘空间来完成该文件的写操作，或者由于没有足够的内存可用，分配缓冲区可能失败。

The first copy (see Figure 1) is performed by the direct memory access (DMA) engine, which reads file contents from the disk and stores them into a kernel address space buffer.

直接内存存取(direct memory access, DMA)引擎执行了第一次拷贝(参见图1)，它从磁盘中读取文件内容，然后将它们存储到一个内核地址空间缓存区中。

When the main buffer pools are configured too large, it is possible that they will not fit into the addressable memory space.

如果主缓冲池配置得太大，则可能出现主缓冲池不适合可寻址内存空间的情况。

But is there really no way of making memory Shared security between user space and kernel when they are just used as a buffer?

但真的没有办法让用户空间和内核之间共享内存的安全时，他们只是作为一个缓冲？
