CVE-2026-10686 Missing hop-limit decrement on IPv6 forwarding path allows unbounded packet looping (DoS) in Zephyr routers

Zephyr's IPv6 forwarding path re-sent routed unicast packets without ever decrementing the IPv6 hop limit. Both routing branches of ipv6routepacket subsys/net/ip were affected: the explicit-route path netroutepacket and the on-link cross-interface path netroutepacketif. Each set the packet...

The vulnerability of the DVMRP (Distance Vector Multicast Routing Protocol) implementation in Juniper Networks’ Junos OS-based QFX10K routers allows a attacker to cause service interruptions.

The vulnerability of the DVMRP Distance Vector Multicast Routing Protocol implementation in Juniper Networks’ Junos OS-based QFX10K routers stems from packet looping due to incorrect comparison of Ethernet segment identifiers. Exploiting this vulnerability can allow a malicious actor to cause...
