Secrets Best Not Shared: DNS Privacy Enhancements for the Constrained IoT

Attackers often identify DNS traffic to disrupt or compromise Internet services. While prior work has focused on encrypting queries using DNS over TLS, HTTPS, or QUIC to counter such attacks, we consider IETF protocols designed for resource-constrained IoT devices and empirically analyze the...

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-2026-36957

Dbit N300 T1 Pro Easy Setup Wireless Wi-Fi Router V1.0.0 is vulnerable to Denial of Service via the boa web server URI handler. By initiating a high-volume flood of HTTP GET requests to non-existent URIs, an attacker can exhaust critical system resources, including file descriptors and memory...

CVE-2026-40914

A flaw was found in Apache ActiveMQ Artemis STOMP. An authenticated user with send or consume permission on an address can change that address's routing-type even without createAddress. As a result, send or consume operations that should be rejected for an unsupported routing-type may succeed,...

CVE-2025-61971

A flaw was found in the microcode that manages NBIO registers. A local attacker with administrative privileges could exploit a missing security control, allowing them to alter critical system configurations. This could compromise the integrity of virtual machines protected by Secure Encrypted...

CVE-2026-34019

When Bidirectional Forwarding Detection BFD is configured in Static and Dynamic routing protocols, undisclosed traffic can cause the Traffic Management Microkernel TMM to stop processing BFD packets and cause the configured routing protocol to fail over. Note: Software versions which have reached...

CVE-2026-22726

Route Services can be leveraged to send app traffic to network destinations outside of an app's configured egress rules. As a result, a malicious developer with access to Cloudfoundry could configure a route-service that would allow it to send requests to HTTP services on internal networks...

CVE-2026-40910

frp is a fast reverse proxy. From 0.43.0 to 0.68.0, frp contains an authentication bypass in the HTTP vhost routing path when routeByHTTPUser is used as part of access control. In proxy-style requests, the routing logic uses the username from Proxy-Authorization to select the routeByHTTPUser...

CVE-2026-9054

An attacker sending tcp, il, rudp, rudp, or gre packets with a length less than the header size would trigger a kernel panic...

CVE-2026-7473

CVE-2026-7473 affects Arista EOS devices where a tunnel decapsulation config (VXLAN, decap-groups, GRE) can cause the switch to decapsulate and forward unintended tunneled packets whose destination matches the decap IP. Root cause: lack of verification of the tunnel protocol type leading to proce...

CVE-2026-7473 Arista EOS Unexpected Tunnel Protocol Decapsulation and Forwarding Bypass

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...
