详细信息

漏洞类型

竞争条件问题

漏洞描述

Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。NFSv4 implementation是其中的一个分布式文件系统协议。Linux kernel 2.x至4.8.3之前的4.x版本中的mm/gup.c文件存在竞争条件漏洞，该漏洞源于程序没有正确处理copy-on-write(COW)功能写入只读内存映射。本地攻击者可利用该漏洞获取权限。

修复建议

为该漏洞应用补丁，可从Linux内核GIT存储库获得： https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=19be0eaffa3ac7d8eb6784ad9bdbc7d67ed8e619
