A Denial of Service (DoS) vulnerability in Palo Alto Networks PAN-OS software causes the firewall to unexpectedly reboot when processing a specially crafted LLDP frame sent by an unauthenticated adjacent attacker. Repeated attempts to initiate this condition causes the firewall to enter maintenance mode.

This issue does not apply to Cloud NGFWs or Prisma Access software.
