CVE-2015-6359 is a vulnerability of currently unknown severity. The Neighbor Discovery (ND) protocol implementation in the IPv6 stack in Cisco IOS 15.3(3)S0.1 on ASR devices mishandles internal tables, which allows remote attackers to cause a denial of service (memory consumption or device crash) via a flood of crafted ND messages, aka Bug ID CSCup28217.. EPSS estimates a 0.91% chance of exploitation in the next 30 days.
