Oct 14 PATCH SHIPPED — CVE-2026-94640 (Red Hat Enterprise Linux 9). Fixed in Red Hat Enterprise Linux 9 0:1.2.6-7.el9_8.1.
Description
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.
