Title: Linux kernel net/xfrm/xfrm_policy.c文件拒绝服务漏洞

Description:

Linux kernel是美国Linux基金会发布的操作系统Linux所使用的内核。

Linux kernel 4.12.3及之前的版本中的net/xfrm/xfrm_policy.c文件存在安全漏洞，该漏洞源于程序未能检测xfrm_userpolicy_id is XFRM_POLICY_MAX的dir值。本地攻击者可借助XFRM_MSG_MIGRATE xfrm Netlink消息利用该漏洞造成拒绝服务（越边界访问）。

Severity: 低

Summary

net/xfrm/xfrm_policy.c in the Linux kernel through 4.12.3, when CONFIG_XFRM_MIGRATE is enabled, does not ensure that the dir value of xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which allows local users to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via an XFRM_MSG_MIGRATE xfrm Netlink message.
