| CVE-2026-73443 | Med | 0.31 | 4.7 | 0.00 | Sep 16, 2026 | On affected platforms running Arista EOS with VRRPv2 IP-AH authentication configured, an unauthenticated attacker within the same layer 2 network segment on which VRRP is running can capture a legitimate authenticated VRRP advertisement and replay it indefinitely. Replayed… | ||
| CVE-2026-73444 | Med | 0.31 | 4.7 | 0.00 | Sep 15, 2026 | On affected platforms running Arista EOS with VRRPv2 IP Authentication Header (IP-AH) authentication configured, an unauthenticated attacker with access to the layer 2 network segment on which VRRP is running could bypass VRRP authentication and claim the virtual router master… | ||
| CVE-2026-73451 | Med | 0.31 | 4.8 | 0.00 | Sep 15, 2026 | On affected platforms running Arista EOS with dual switch cards and with ingress Security ACLs configured on Switched Virtual Interfaces (SVI) in shared mode, restarting of the secondary switchcard forwarding agent or insertion of secondary switchcard, can cause security ACLs on… | ||
| CVE-2025-7048 | Med | 0.28 | 4.3 | 0.00 | Jan 6, 2026 | On affected platforms running Arista EOS with MACsec configuration, a specially crafted packet can cause the MACsec process to terminate unexpectedly. Continuous receipt of these packets with certain MACsec configurations can cause longer term disruption of dataplane traffic. | ||
| CVE-2024-7095 | Med | 0.28 | 4.3 | 0.00 | Jan 10, 2025 | On affected platforms running Arista EOS with SNMP configured, if “snmp-server transmit max-size” is configured, under some circumstances a specially crafted packet can cause the snmpd process to leak memory. This may result in the snmpd process being terminated (causing… | ||
| CVE-2026-73440 | Med | 0.27 | 4.2 | 0.00 | Sep 16, 2026 | On affected platforms running Arista EOS with Simple Network Management Protocol (SNMP) configured, SNMPv3 local or remote user credentials may be exposed as a one-way hashed, localized key value within the device's running and sanitized configurations. An authenticated user who… | ||
| CVE-2026-19640 | Med | 0.27 | 4.2 | 0.00 | Sep 16, 2026 | On affected platforms running Arista EOS, an authenticated user with access to the gNMI (gRPC Network Management Interface) may receive incorrect authorization results, potentially allowing access beyond their currently assigned permissions. This issue was discovered internally… | ||
| CVE-2025-3456 | Low | 0.25 | 3.8 | 0.00 | Aug 25, 2025 | On affected platforms running Arista EOS, the global common encryption key configuration may be logged in clear text, in local or remote accounting logs. Knowledge of both the encryption key and protocol specific encrypted secrets from the device running-config could then be… |
