CVE-2026-68554

A flaw was found in Coturn, a free open source implementation of TURN and STUN Session Traversal Utilities for NAT Server. An on-path attacker can exploit this vulnerability on plain UDP or TCP by appending attributes after the MESSAGE-INTEGRITY field in an authenticated STUN request. This allows...

CVE-2026-74543

A flaw was found in the Linux kernel's UDP tunnel network interface controller NIC offload code. When a device registration fails, the system may not properly unregister the NIC tunnel, leading to a permanent memory leak. This can result in resource exhaustion over time, potentially causing a...
