CVE-2026-76465

Name of the Vulnerable Software and Affected Versions Cisco NX-OS Software for Cisco Nexus 3000 Series Switches (affected versions not specified) Cisco NX-OS Software for Cisco Nexus 9000 Series Switches (affected versions not specified)

Description An issue exists in the MPLS Operation, Administration, and Maintenance (OAM) feature. This is caused by improper validation when the system processes an MPLS echo-request packet. An unauthenticated remote attacker can exploit this by sending a crafted MPLS echo-request to an IP address on the device, potentially leading to arbitrary code execution with root privileges or a denial of service (DoS) condition caused by process crashes and device reloads.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
