NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-firmware package and not the kernel-uek-firmware package as distributed by Oracle. See How to fix? for Oracle:6 relevant fixed versions and status.

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.
