Threats Tagged 'cve-2026-76486'

A critical vulnerability exists in the VXLAN Operation, Administration, and Maintenance (OAM) feature of Cisco NX-OS Software, known as NGOAM. This flaw allows an unauthenticated remote attacker to execute arbitrary code with root privileges or cause a denial-of-service (DoS) by sending specially crafted packets to an affected device. The issue arises from improper input validation of IP traffic when NGOAM is enabled. Exploitation can lead to process crashes and device reloads, severely impacting availability.

A vulnerability in the VXLAN Operation, Administration, and Maintenance (OAM) feature of Cisco NX-OS Software, known as NGOAM, could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a Denial-of-Service (DoS) on an affected device. This vulnerability is due to improper input validation of IP traffic when the NGOAM feature is enabled. An attacker could exploit this vulnerability by sending crafted packets to an IP interface on an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes resulting in a reload and DoS condition.
