CVE-2026-2379

The CVE-2026-2379 issue affects Arista EOS on hardware IPSec platforms where anti-replay is disabled. When IPsec is enabled, specific events (physical interface flaps or certain agent restarts) can trigger IPsec tunnel re-establishment using existing SAs, causing sequence number mismatches betwee...

CVE-2026-7473

On affected platforms running Arista EOS where a tunnel decapsulation configuration—such as VXLAN Virtual Extensible LAN, decap-groups, or a GRE Generic Routing Encapsulation tunnel interface—is present, the switch will incorrectly decapsulate and forward other unexpected tunneled packet with a...

CVE-2025-5088 Arista CloudVision Exchange (CVX) Cluster Privilege Escalation via MCS Redis Session

An authenticated Redis session could be used to obtain full root access to all servers in the CVX cluster. Note that this would require an attacker to have both network access to the Redis service on a CVX server and the Redis password. Please note that all Redis communication, including...

CVE-2025-5088

CVE-2025-5088 affects Arista CloudVision Exchange (CVX) via an authenticated Redis session that could grant full root access to all CVX servers. Exploitation requires network access to the Redis service and the Redis password, and Redis traffic is plaintext (TLS support tracked separately). The i...

CVE-2025-5090 Arista CloudVision Exchange Cluster Instability via Unexpected Switch Messages

CVX is not resilient to unexpected messages from a connected switch. This leads to agent crashes on CVX causing instability in the CVX cluster. An attacker could use this behavior to create a denial of service DoS scenario. Note that this would require the attacker to have a high privilege access...

CVE-2025-5090

CVE-2025-5090 affects Arista CloudVision Exchange (CVX) in Arista EOS-based deployments. The issue arises when CVX processes unexpected messages from a connected switch, leading to agent crashes on CVX and instability in the CVX cluster, enabling a DoS under high-privilege conditions on the conne...

CVE-2025-5089 Arista EOS SysDB Agent Denial of Service via Malformed CVX Client/Server Messages

In a CVX cluster, an EOS switch connected to a CVX server is not resilient to certain malformed messages received from the connected CVX server. Similarly, the CVX server is not resilient to certain malformed messages received from the connected EOS switch. This leads to either a Sysdb agent cras...

CVE-2025-5089

CVE-2025-5089 describes a DoS condition in Arista EOS CVX deployments where malformed messages between a CVX server and connected EOS Switch can crash SysDB on EOS or destabilize the CVX cluster, requiring high-privilege access to send crafted TCP packets. Affected products are Arista EOS with Cl...
