Vulnerability from github
A vulnerability in the Link Layer Discovery Protocol (LLDP) implementation for Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition when the device unexpectedly reloads. The vulnerability is due to improper input validation of certain type, length, value (TLV) fields of the LLDP frame header. An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface on the targeted device. A successful exploit could allow the attacker to cause the switch to reload unexpectedly.

The following example shows the output of the show version CLI command for a device that is running Cisco FXOS Software Release 2.2(2.14), as identified in the Package-Vers field of the command output:\r\n\r\n\r\nQP4120B1 # scope system\r\nQP4120B1 /system # show version\r\nFPRM:\r\nRunning-Vers: 4.2(2.15)\r\nPackage-Vers: 2.2(2.14)\r\nActivate-Status: Ready\r\n Determining the Cisco NX-OS Software Release\r\nAdministrators can determine the release of Cisco NX-OS Software running on a device by using the show version command in the device CLI.

Vulnerability from variot
A vulnerability in the Link Layer Discovery Protocol (LLDP) implementation for Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition when the device unexpectedly reloads. The vulnerability is due to improper input validation of certain type, length, value (TLV) fields of the LLDP frame header. An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface on the targeted device. A successful exploit could allow the attacker to cause the switch to reload unexpectedly. Cisco FXOS and Cisco NX-OS The software contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. CiscoFXOS is a Firepower scalable operating system. Cisco NX-OS is a network operating system for Cisco Nexus Series Ethernet Switches and MDS Series Fibre Channel Storage Area Network Switches. This issue is being tracked by Cisco Bug IDs CSCuc98542, CSCvf23367, CSCvj94174 and CSCvj96148. Cisco Firepower 4100 Series Next-Generation Firewalls are all products of Cisco (Cisco). Cisco Firepower 4100 Series Next-Generation Firewalls is a 4100 series firewall device. Nexus 1000V Series Switches is a 1000V series switch device. FXOS Software is a set of firewall software running on Cisco security appliances. NX-OS Software is a set of data center-level operating system software running on Cisco switch equipment
