Arista EOS VLAN Isolation Breach Vulnerability on Layer 2 Ports

A vulnerability exists in Arista EOS on certain platforms, where ingress traffic on Layer 2 ports may be incorrectly forwarded to ports linked with different VLANs. This misrouting can lead to a violation of VLAN isolation and segmentation, allowing unintended traffic flow between VLANs.

Impact

Exploitation of this vulnerability can cause unauthorized traffic to be forwarded between VLANs, disrupting segmentation and potentially allowing sensitive data to be intercepted or manipulated.
