N/A
Vulnerability Description
The mremap system call (do_mremap) in Linux kernel 2.4.x before 2.4.21, and possibly other versions before 2.4.24, does not properly perform bounds checks, which allows local users to cause a denial of service and possibly gain privileges by causing a remapping of a virtual memory area (VMA) to create a zero length VMA, a different vulnerability than CAN-2004-0077.

Linux kernel do_mremap本地权限提升漏洞
Vulnerability Description
Linux是一款开放源代码操作系统。 Linux内核中的内存管理代码mremap(2)系统调用缺少正确边界检查，本地攻击者可以利用这个漏洞进行权限提升攻击，可以ROOT权限在系统上执行任意指令。 mremap系统调用被应用程序用来改变映射区段(VMAs)的边界地址。一般的VMA覆盖至少一个内存页(在i386架构上为4kB)，do_mremap()内核代码执行重映射虚拟内存区域时发现缺少正确的边界检查，可导致建立0字节长度的虚拟内存区域。 错误的分配虚拟内存区域可破坏其他内核内存管理子程序的操作，最终导致不
