Complete persistent denial of service in Juniper Networks Junos OS Evolved on PTX Series routers allows authenticated, low-privilege network attackers to crash the evo-aftmand service with no automatic recovery. The vulnerability triggers when PCEP-provisioned colored SRTE policy tunnels with 32-bit ASN values (greater than 65,535) in the Originator ASN field are monitored via gRPC, causing permanent forwarding plane failure until manual system restart. Affects multiple versions through 25.2 release train. No public exploit identified at time of analysis.
