CVE-2018-10938

Disclosure Date: August 27, 2018 •
CVE-2018-10938 CVSS v3 Base Score: 5.9
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

A flaw was found in the Linux kernel present since v4.0-rc1 and through v4.13-rc4. A crafted network packet sent remotely by an attacker may force the kernel to enter an infinite loop in the cipso_v4_optptr() function in net/ipv4/cipso_ipv4.c leading to a denial-of-service. A certain non-default configuration of LSM (Linux Security Module) and NetLabel should be set up on a system before an attacker could leverage this flaw.
