According to its self-reported version, Cisco NX-OS System Software in ACI Mode is affected by a denial of service vulnerability due to incomplete input validation of specific OSPFv3 packet. An unauthenticated, remote attacker can exploit this, by sending a malicious OSPFv3 link-state advertisement (LSA) to an affected device, to cause the OSPFv3 process to crash and restart multiple times, causing the affected device to reload.
Please see the included Cisco BIDs and Cisco Security Advisory for more information.
