CVE-2016-9755

Priority
Medium
Description
The netfilter subsystem in the Linux kernel before 4.9 mishandles IPv6
reassembly, which allows local users to cause a denial of service (integer
overflow, out-of-bounds write, and GPF) or possibly have unspecified other
impact via a crafted application that makes socket, connect, and writev
system calls, related to net/ipv6/netfilter/nf_conntrack_reasm.c and
net/ipv6/netfilter/nf_defrag_ipv6_hooks.c.
Ubuntu-Description
Dmitry Vyukov, Andrey Konovalov, Florian Westphal, and Eric Dumazet
discovered that the netfiler subsystem in the Linux kernel mishandled IPv6
packet reassembly. A local user could use this to cause a denial of service
(system crash) or possibly execute arbitrary code.
