EUVD-2026-30488

The MCP Registry provides MCP clients with a list of MCP servers, like an app store for MCP servers. Prior to 1.7.7, the Registry's HTTP-based namespace verification POST /v0/auth/http, POST /v0.1/auth/http uses safeDialContext internal/api/handlers/v0/auth/http.go:67-110 to refuse dialling...

CVE-2026-43057

A flaw was found in the Linux kernel's networking subsystem. Incorrect handling of tunneled IPv6 traffic, specifically when processing packets with IPv6 extension headers or without an inner IP protocol, can cause the system to improperly revert to a software processing path. This issue may lead ...

CVE-2025-23018

IPv4-in-IPv6 and IPv6-in-IPv6 tunneling RFC 2473 do not require the validation or verification of the source of a network packet, allowing an attacker to spoof and route arbitrary traffic via an exposed network interface. This is a similar issue to CVE-2020-10136...

kernel: some ipv6 protocols not encrypted over ipsec tunnel

A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data...

Teredo Server Detection

The remote host is running a Teredo server. Teredo is a protocol for tunneling IPv6 over UDP, and is used to give nodes the ability to obtain IPv6 connectivity behind IPv4 network address translation NAT devices. A Teredo server is a node that is connected to both IPv4 and IPv6 networks. C Tenabl...
