NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-devel package and not the kernel-uek-devel package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel through 4.9.9 allows attackers to cause a denial of service (system crash) via (1) an application that makes crafted system calls or possibly (2) IPv4 traffic with invalid IP options.
