Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.12.3

Description The issue is related to the net/xfrm/xfrm policy.c file in the Linux kernel. It does not properly validate the dir value of xfrm userpolicy id when CONFIG XFRM MIGRATE is enabled. This can be exploited by local users via an XFRM MSG MIGRATE xfrm Netlink message, potentially leading to a denial of service due to out-of-bounds access or other unspecified impacts.

Recommendations For Linux kernel versions prior to 4.12.3, update to version 4.12.3 or later to resolve the issue.
