What is CVE-2026-76485?

A security weakness in the NGOAM feature of Cisco NX-OS Software could enable an unauthenticated remote attacker to execute arbitrary code with root privileges or induce a Denial-of-Service (DoS) on affected devices. This issue arises from inadequate input validation of IP traffic when the NGOAM feature is activated. By sending specially crafted packets to an IP interface on an impacted device, an attacker can exploit this vulnerability, leading to process crashes, system reloads, and potentially uncontrolled execution of system commands.
