Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to function call with incorrect argument type error in the sensor interface. A remote user can cause a complete Denial of Service (DoS).

If colored SRTE policy tunnels are provisioned via PCEP, and gRPC is used to monitor traffic in these tunnels, evo-aftmand crashes and doesn't restart which leads to a complete and persistent service impact.

The system has to be manually restarted to recover.
