CVE-2016-7917 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.51% chance of exploitation in the next 30 days.
