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

Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 8; Red Hat Red Hat Enterprise Linux 9; Red Hat Red Hat OpenShift Container Platform 4.22 Veröffentlicht: (vor 1 Monat)

Beschreibung

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.

Schwachstellentyp (CWE): CWE-400
