The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux kernel before 4.5 does not check whether a batch message's length field is large enough, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (infinite loop or out-of-bounds read) by leveraging the CAP_NET_ADMIN capability.

CVE-2016-7913 [MEDIUM] Linux kernel (Xenial HWE) vulnerabilities
Title: Linux kernel (Xenial HWE) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
USN-3312-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu
14.04 LTS.
It was discovered that the netfilter netlink implementation in the Linux
kernel did not properly validate batch messages. A local attacker with the
CAP_NET_ADMIN capability could use this to expose sensitive information or
cause a denial of service. (CVE-2016-7917)
