Name of the Vulnerable Software and Affected Versions Cisco NX-OS on the Nexus 1000V (affected versions not specified)

Description The issue is related to the insufficient prioritization of heartbeat messages between a Virtual Ethernet Module (VEM) and a Virtual Supervisor Module (VSM). This allows remote attackers to cause a denial of service by flooding the system with UDP packets, resulting in a false report of VEM unavailability. The attacker would likely need access to a trusted internal network to exploit this issue.

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