CVE-2026-94640

CVE-2026-94640 · Rpcbind: unbounded memory allocation in rpcbind statistics tracking allows unauthenticated remote denial of service

This page contains facts from public vulnerability sources. Check the original advisory before updating.

A flaw was found in rpcbind. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by sending a large number of unique requests. The rpcbind service records previously unseen RPC (Remote Procedure Call) statistics in unbounded in-memory lists, leading to persistent memory growth and increased CPU usage. This can degrade or exhaust service availability.
