Linux Kernel IPv6 VTI Subsystem Use-After-Free Local Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of...

Linux Kernel IPv6 Neighbour Discovery Uninitialized Memory Information Disclosure Vulnerability

This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handlin...

PT-2026-91110

A vulnerability was detected in D-Link DIR-878 120B05. This affects the function SetDynamicDNSIPv6Settings of the component Dynamic DNS IPv6 Settings. The manipulation of the argument IPv6Address/Hostname results in stack-based buffer overflow. The attack may be launched remotely...

CVE-2026-80976

A flaw was found in the Linux kernel's IPv6 Segment Routing seg6 implementation. An unprivileged user can exploit this vulnerability by injecting a specially crafted IPv6 packet. This can lead to an out-of-bounds read, potentially causing a system crash and resulting in a Denial of Service DoS...

CVE-2026-89561

A flaw was found in the Linux kernel's IPv6 Routing Protocol for Low-Power and Lossy Networks RPL implementation. A remote attacker could send specially crafted IPv6 packets to a vulnerable system while manipulating the network interface's Maximum Transmission Unit MTU, which defines the largest...

CVE-2026-89698

A flaw was found in the Linux kernel's nfsd component. When an IPv6 NFS client is connected, the nfsdgenlrpcstatuscomposemsg function incorrectly handles address fields, leading to an out-of-bounds read. A local unprivileged attacker can exploit this vulnerability to disclose sensitive kernel...

FrontMCP and mcp-from-openapi have bypass of OpenAPI external $ref SSRF fix

Summary The published fix for GHSA-v6ph-xcq9-qxxj / CVE-2026-39885 added a direct hostname denylist for OpenAPI external $ref dereferencing, but the latest patched dependency mcp-from-openapi 2.3.0 still makes backend-origin requests to loopback when the target is reached through hostname...
