Vulnerability from fkie_nvd - Published: 2018-10-08 17:29 - Updated: 2026-06-17 01:46

Severity

4.4 (Medium) - CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H

Summary

The Linux kernel 4.14.67 mishandles certain interaction among XFRM Netlink messages, IPPROTO_AH packets, and IPPROTO_IP packets, which allows local users to cause a denial of service (memory consumption and system hang) by leveraging root access to execute crafted applications, as demonstrated on CentOS 7.
