2018-07-07漏洞描述
在fs/inode.c:inode_init_owner()函数逻辑中发现了一个漏洞，该漏洞允许本地用户创建具有非预期组所有权的文件，并使用组执行和SGID权限位设置，在目录为SGID且属于某个组的情况下，并且由不是该组成员的用户可写。这可能导致在不应该的情况下授予过度的权限。解决建议
目前厂商已发布升级补丁以修复漏洞，补丁获取链接：https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0fa3ecd87848c9c93c2c828ef4c3a8ca36ce46c7
