CVE-2026-73462: Arista Networks EOS, грешка в паметта

Описание

Оригинално описание

On affected platforms running Arista EOS with IGMP (Internet Group Management Protocol) snooping configured (enabled by default on all VLANs), a network-adjacent unauthenticated attacker can send malformed network packets on an affected VLAN to cause the IGMP snooping agent to terminate unexpectedly. This results in a temporary disruption of multicast traffic management, which may cause multicast traffic to be flooded to all ports of the affected VLAN until the service recovers. Repeated exploitation could result in a prolonged loss of intended multicast forwarding behavior.
