CVE-2016-6355
Memory leak in Cisco IOS XR 5.1.x through 5.1.3, 5.2.x through 5.2.5, and 5.3.x through 5.3.2 on ASR 9001 devices allows remote attackers to cause a denial of service (control-plane protocol outage) via crafted fragmented packets, aka Bug ID CSCux26791.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.87%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
