Last modified

CVE-2017-11600 is a high-severity vulnerability rated 7/10 on the CVSS scale. 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.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
