Synopsis

The remote CentOS host is missing a security update for rpcbind.

Description

The remote CentOS Linux 9 host has a package installed that is affected by a vulnerability as referenced in the rpcbind-1.2.6-8.el9 build changelog.

- 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.
(CVE-2026-94640)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the CentOS 9 Stream rpcbind package.
