P4Runtime is disabled by default in Arista EOS. By crafting a malicious packet during the initiation of a P4Runtime session, an attacker can obtain complete administrative control over the compromised switch.\n\nThis issue was discovered internally by Arista, and the company is not aware of any malicious exploitation of this vulnerability in customer networks.",
