CVE-2016-7917

Priority
Low
Description
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.
Ubuntu-Description
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.
