Detailed vulnerability description
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to missing release of memory after effective lifetime error in the Packet Forwarding Engine (PFE). A remote non-authenticated attacker can cause a Denial of Service (DoS).
In case of channelized Modular Interface Cards (MICs), every physical interface flap operation will leak heap memory.
Over a period of time, continuous physical interface flap operations causes local FPC to eventually run out of memory and crash.
