"A vulnerability in the Cisco Fabric Services component of Cisco FXOS
Software and Cisco NX-OS Software could allow an unauthenticated,
remote attacker to cause a denial of service (DoS) condition on an
affected device. The vulnerability exists because the affected
software insufficiently validates Cisco Fabric Services packets when
the software processes packet data. An attacker could exploit this
vulnerability by sending a maliciously crafted Cisco Fabric Services
packet to an affected device. A successful exploit could allow the
attacker to cause a buffer overflow condition on the device, which
could cause process crashes and result in a DoS condition on the
device. This vulnerability affects Firepower 4100 Series Next-
Generation Firewalls, Firepower 9300 Security Appliance, MDS 9000
Series Multilayer Switches, Nexus 2000 Series Fabric Extenders, Nexus
3000 Series Switches, Nexus 3500 Platform Switches, Nexus 5500
Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series
Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches,
Nexus 9000 Series Switches in standalone NX-OS mode, Nexus 9500
R-Series Line Cards and Fabric Modules, UCS 6100 Series Fabric
Interconnects, UCS 6200 Series Fabric Interconnects, UCS 6300 Series
Fabric Interconnects. Cisco Bug IDs: CSCvd69960, CSCve02463,
CSCve04859, CSCve41530, CSCve41537, CSCve41541, CSCve41557.
