首先,kernel检查关键字是不是 ‘root=’, ‘nfsroot=’, ‘nfsaddrs=’, ‘ro’, ‘rw’, ‘debug’或’init’,然后内核在bootsetups数组里搜索于该关键字相关联的已注册的处理函数,如果找到相关的已注册的处理函数,则调用这些函数并把关键字后面的值作为参数传递给这些函数。比如,你在启动时设置参数name=a,...
等待poll_list线程执行完毕,并且我们分配的kmalloc-32被错误释放,分配大量的seq_operations,运气好可以正好被分配到我们释放的kmalloc-32,形成UAF,这样我们就可以利用UAF修改seq_operations->start指针指向提权代码。 提权可以参考上一篇文章,利用栈上的残留值来bypass kaslr。 exp #ifndef _GNU_SOURCE #define _GNU_SOU...
