Description

On affected platforms running Arista EOS, ACL policies may not be enforced. IPv4 ingress ACL, MAC ingress ACL, or IPv6 standard ingress ACL enabled on one or more ethernet or LAG interfaces may result in ACL policies not being enforced for ingress packets. This can cause incoming packets to incorrectly be allowed or denied. The two symptoms of this issue on the affected release and platform are: 1) Packets which should be permitted may be dropped and, 2) Packets which should be dropped may be permitted. This issue was discovered internally and Arista is not aware of any malicious uses of this issue in customer networks.
